solve the equation
-2v-7=23
A. 15
B. 8
C. -8
D. -15
yes
my answer is D.... is D correct?
To solve the equation -2v - 7 = 23, we need to isolate the variable v.
Step 1: Add 7 to both sides of the equation to eliminate the constant term on the left side:
-2v - 7 + 7 = 23 + 7
Simplifying this gives:
-2v = 30
Step 2: Divide both sides of the equation by -2 to solve for v:
(-2v) / (-2) = 30 / (-2)
Simplifying this gives:
v = -15
Therefore, the solution to the equation -2v - 7 = 23 is v = -15.
The correct answer is option D. -15.
To solve the equation -2v - 7 = 23, we need to isolate the variable v on one side of the equation. Here's how to do it:
Step 1: Add 7 to both sides of the equation to get rid of the constant term on the left side:
-2v - 7 + 7 = 23 + 7
-2v = 30
Step 2: Divide both sides of the equation by -2 to solve for v:
(-2v) / -2 = 30 / -2
v = -15
So, the solution to the equation -2v - 7 = 23 is v = -15.
Therefore, the correct answer is (D) -15.
