Question

Find an expression which represents the sum of (-X – 7) and (-9x + 6) insimplest terms.

Answer 1

Let's sum the given expressions.

$(-x-7)+(-9x+6)$

We have to reduce like terms. -x and -9x are like terms. -7 and 6 are like terms.

$-x-9x-7+6=-10x-1$

Therefore, the simplest expression is -10x - 1.
