Question

solve. check each ans

1. 3v - 12 = 15

Explanation:

Step1: Isolate the variable term

Add 12 to both sides of the equation.
$3v - 12 + 12 = 15 + 12$
$3v = 27$

Step2: Solve for v

Divide both sides by 3.
$\frac{3v}{3} = \frac{27}{3}$
$v = 9$

Step3: Verify the solution

Substitute $v=9$ into the original equation.
$3(9) - 12 = 27 - 12 = 15$, which matches the right-hand side.

Answer:

$v=9$
