Solving
14 = 31.7 + -3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3x' to each side of the equation.
14 + 3x = 31.7 + -3x + 3x

Combine like terms: -3x + 3x = 0
14 + 3x = 31.7 + 0
14 + 3x = 31.7

Add '-14' to each side of the equation.
14 + -14 + 3x = 31.7 + -14

Combine like terms: 14 + -14 = 0
0 + 3x = 31.7 + -14
3x = 31.7 + -14

Combine like terms: 31.7 + -14 = 17.7
3x = 17.7

Divide each side by '3'.
x = 5.9

Simplifying
x = 5.9
