Question

What is the equation?
3.7 = 5x + 12.2

Answer 1

x = -1.7.

Explanation:

3.7 = 5x + 12.2

Subtract 3.7 from both sides:

0 = 5x + 12.2 - 3.7

0 = 5x + 8.5

Subtract 5x from both sides:

-5x = 8.5

x = 8.5 / -5

x = -1.7.

Answer 2

x= -1.7

Explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.
