Answer
x = $\frac{-11}{3}$
Work Step by Step
Check:
Replace x with -2 in the original equation
3 (2x + 5) = -7
3(2*-2 + 5) = -7
3(-4 +5) = -7
3(1) = -7
3 =-7
False
The first step on the left side should have been 3 (2x + 5) is 6x + 15.
6x +15 = -7
Subtract 15 to both sides
6x +15 - 15 = -7 -15
6x = -22
Finally, divide both sides by 6
$\frac{6x}{6}$ = $\frac{-22}{6}$
x = $\frac{-11}{3}$
The solution is $\frac{-11}{3}$
