(B)8
(C)-8
(D)-15
Am I right?
No. Watch your signs.
well can you help me solve it?
-2v-7=23
Add 7 to both sides.
-2v = 30
Divide both sides by - 2
Watch your signs.
To solve the equation -2v - 7 = 23, you need to isolate the variable v. Here's how to do it step by step:
Step 1: Start with the given equation -2v - 7 = 23.
Step 2: Add 7 to both sides of the equation to get rid of the constant term on the left side. The equation becomes -2v = 23 + 7.
Simplified, this is -2v = 30.
Step 3: Now, divide both sides of the equation by -2 to solve for the variable v. You would get v = 30 divided by -2.
Performing the division, you get v = -15.
Therefore, the correct answer is (D) -15.
