Solution by Steps
step 1
Solve the equation 3v1=5-3v - 1 = 5 for vv
step 2
Add 11 to both sides: 3v1+1=5+1-3v - 1 + 1 = 5 + 1 which simplifies to 3v=6-3v = 6
step 3
Divide both sides by 3-3: v=63v = \frac{6}{-3} which simplifies to v=2v = -2
step 4
Substitute v=2v = -2 into 2v+72v + 7: 2(2)+72(-2) + 7
step 5
Simplify the expression: 2(2)+7=4+7=32(-2) + 7 = -4 + 7 = 3
Answer
The value of 2v+72v + 7 given that 3v1=5-3v - 1 = 5 is 33.
