So in this case, youвЂ™d write a 2 beside the 1 to get 12. Then, if there are any numbers left under the division bar, bring them down to the same row as the remainder. Write the number 2 above the bar, and the remainder вЂ“В in this case, 1 вЂ“ below the 7. In this case, youвЂ™re calculating how many times 3 goes into 7. Substituting this value for y into 1 gives: 2(2x 1) + x 8 4x. Example Solve the two simultaneous equations: 2y + x 8 1 1 + y 2x 2 from 2 y 2x -1 subtract 1 from each side. Should your solutions be вЂstrangeвЂ™ fractions such as 9/13 the chances are youвЂ™ve made a slip check your algebra. Then, calculate how many times 3 goes into the first number under the division bar. NOTE:With this method you need to take particular care with your algebra. For example, if you want to calculate 72 Г· 3, place 72 under the division bar and 3 outside of it.

To do long division, write the number you want to divide under the division bar, and place the number you want to divide by outside of the bar. For larger numbers, it's helpful to spend time reviewing the multiplication tables. For example, 6 Г· 2 is 3, because 3 goes into 6 two times. We use a similar technique for long division in algebra.To do simple division, think about how many times one number can go into another number. Our result means that the answer is 1,813 with remainder 7, or:

We continue until we get to the last number, 6. However, once you know it, you can write in this language You, too, can write algebraic equations.

We bring the 5 (the next number after 3) down. Mathematical equations are telling you to do something, giving you information on how to respond, or come up with an answer. Now, to divide this, (assuming we do not have a calculator) we could proceed as follows. Long Division in AlgebraД«efore we do an example using algebra, letвЂ™s remember how to do long division with numbers first. If ever you have to have advice with algebra and in particular with Quadratic Equation Division or equations and inequalities come visit us at. You can check your answer by multiplying (3x + 1) by (x 4) and youll get (3x 2 11x 4). Step 5: Subtract the 4th row from the 3rd: So (3x 2 11x 4) Г· (x 4) 3x + 1. Next, multiply (1) by (x 4) to get the 4th row. So I multiply each element of the top by x and each element of the bottom by x and I get: Our answer is 1 and we write '+ 1' at the top of our long division. Now we should check our answer by plugging in x 7 back into the original equation: 3x - 6 15. I am really just multiplying by '1' and not changing the original value of the fraction - just changing its form. It's easiest to do the addition and subtraction steps first with this kind of equation. So if I just multiply top and bottom by x, it will simplify everything by removing the fractions on top and bottom. I recognise that I have '/ x' in both the numerator and denominator. The x's cancelled out, and we have our final answer, which cannot be simplified any more. To divide by a fraction, you multiply by the reciprocal: We think of the right side as a division of the top by the bottom: We do likewise with the bottom expression (denominator): I take the top expression (numerator) and turn it into a single fraction with denominator x. You can decide which is easier -) Solution 1 - Multiplying by the Reciprocal It is worth seeing both, because they are both useful. I'll show you how to do this two different ways.
