Answer:

v=6

Step-by-step explanation:

-42=4v-18

Add 18 to each side

-42+18=4v-18+18

-24 = 4v

divide each side by 4

Answer:

v = -6

Step-by-step explanation:

Isolate the variable, v. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS =

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, add 18 to both sides:

-42 (+18) = 4v - 18 (+18)

-42 + 18 = 4v

4v = 18 - 42

4v = -24

Next, divide 4 from both sides:

(4v)/4 = (-24)/4

v = -24/4

v = -6

v = -6 is your answer.
