Answer:
Step-by-step explanation:
Combine like terms
3v + 4v
26=7v+12
Subtract 12 from both sides of the equation
26-12
12-12
14=7v
Simplify
so subtract the 12's
Divide both sides of the equation by the same term
14 divided by 7
7 divided by 7
Simplify
do the division and move the term on the other side and it would be
v=2
Solution
v=2
