Answer:

v = 1.3

Explanation:

To solve for one variable, simplify the equation and isolate the variable.

-3.43=-3.1v+2(v-2)+2

Bring all the terms to one side.

0 = 3.43 - 3.1v + 2(v - 2) + 2 <= -3.43 moved to the right becomes 3.43

Distribute across brackets.

0 = 3.43 - 3.1v + (2v - 4) + 2

Collect like terms. (Combine terms with and without the variable separately)

0 = 3.43 - 3.1v + 2v - 4 + 2 <= (-3.1v + 2v) and (3.43 - 4 + 2)

0 = 1.43 - 1.1v

Isolate v.

0 = 1.43 - 1.1v

1.1v = 1.43 <= divide both sides by 1.1

v = 1.3
