Question

Which is a correct first step for solving this equation? -3x+2−5x−7=4x+2

Answer 1

Answer:

(D)$-8x-5=4x+2$

Step-by-step explanation:

The given equation is:

$-3x+2-5x-7=4x+2$

Combining the like terms, we get

$-3x-5x+2-7=4x+2$

$-8x-5=4x+2$

which is the required correct step for solving the given equation.

therefore, again combining the like terms, we get

$-8x-4x=2+5$

$-12x=7$

$x=\frac{-7}{12}$

thus, option D is correct.

Answer 2

D would be the correct answer in this case.
