Combine Like Terms: 5x−12−6x=−10x+7−1

Answer 1

To combine like terms, we add or subtract coefficients that have the same variable.

On the left side of the equation, we have 5x and -6x. Adding them together, we get -1x or just -x. Therefore, the left side of the equation becomes -x - 12.

On the right side of the equation, we have -10x. Therefore, the right side of the equation remains the same, which is -10x + 7 - 1.

Putting it all together, the equation becomes:

-x - 12 = -10x + 7 - 1
