1. -2v-7=-23
Options
15
8
-8
-15
-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.
