-2v-7=-23

add 7 to both sides:
-2v = -16
now divide by -2:
v = 8

i think that is right

To solve the equation -2v - 7 = -23, we need to isolate the variable v on one side of the equation.

Step 1: Start by subtracting 7 from both sides of the equation:
-2v - 7 + 7 = -23 + 7

This simplifies to:
-2v = -16

Step 2: Next, divide both sides of the equation by -2 to solve for v:
(-2v) / -2 = (-16) / -2

Simplifying further gives us:
v = 8

Therefore, the solution to the equation -2v - 7 = -23 is v = 8.
