Question

To isolate a single variable when rearranging equations, move all other variables to the__________of the equation by using ________ on them and remembering to perform that operation _________. Make sure the rearrangement has the target variable

Answer 1

Step-by-step explanation:

To isolate a single variable when rearranging equations, move all other variables to the other side of the equation by using its inverse operation on them and remembering to perform that operation on itself. Make sure the rearrangement has the target variable. For example, we can grab a simple equation such as the one below and isolate x.

x - 5y + 3 = 25 ... first we subtract 3 from both sides

x - 5y = 22 ... now we add 5y to both sides which will cancel out the 5y on the left

x = 22 + 5y

And we finally have the x variable isolated.
