Answer:

-17

Step-by-step explanation:

3x-7=4x+10

Add 7 to both sides & simplify

3x-7=4x+10

+7           +7

3x=4x+17

Subtract 4x from both sides & simplify

3x=4x+17

-4x  -4x

-x=17

*Negative x equals -1*

Divide both sides by -1 & simplify

[tex]\frac{-x}{-1} =\frac{-17}{-1}[/tex]

[tex]x=-17[/tex]
3x-7=4x+10
(get numbers on one side terms on the other)

3x=4x+17

-1x=17
(divide the -1 out)

x=-17
