Which is a correct first step for solving this equation? -3x+2−5x−7=4x+2
a.) -2x-5=4x+2
b.) 2x+5=4x+2
c.) 8x+5=4x+2
d.) -8x-5=4x+2

Respuesta :

D would be the correct answer in this case.

Answer:

(D)[tex]-8x-5=4x+2[/tex]

Step-by-step explanation:

The given equation is:

[tex]-3x+2-5x-7=4x+2[/tex]

Combining the like terms, we get

[tex]-3x-5x+2-7=4x+2[/tex]

[tex]-8x-5=4x+2[/tex]

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

therefore, again combining the like terms, we get

[tex]-8x-4x=2+5[/tex]

[tex]-12x=7[/tex]

[tex]x=\frac{-7}{12}[/tex]

thus, option D is correct.
