7v-10 given that -9v-9=9 simplify the answer. I do not understand the question, can someone help pls.
I believe the question should read:
Evaluate 7v-10 given that -9v-9=9 simplify the answer.
If that's the case, start with
-9v-9=9
and solve for v.
Substitute the (numerical) value of v into 7v-10 to get the answer required.
-6(9-9v)
Certainly! Let's break down the question and solve it step by step.
First, we have the equation -9v - 9 = 9. Our goal is to simplify the expression 7v - 10 based on this equation.
To solve the equation -9v - 9 = 9, we need to isolate the variable 'v'.
Step 1: Add 9 to both sides of the equation:
-9v - 9 + 9 = 9 + 9
-9v = 18
Step 2: Divide both sides of the equation by -9 to solve for 'v':
-9v / -9 = 18 / -9
v = -2
Now let's simplify the expression 7v - 10 using the value of 'v' we found.
Given that v = -2, we substitute the value in the expression:
7v - 10 = 7*(-2) - 10
Simplifying further:
7*(-2) = -14
-14 - 10 = -24
So, the simplified answer for 7v - 10, given -9v - 9 = 9, is -24.
