First subtract each side by 3.7 because you want to isolate x.
6.2x + 3.7 = 22.3
6.2x = 18.6
x = 3
So your answer would be 3! Hope this helped!

Simplifying
6.2x + 3.7 = 22.3
Reorder the terms:
3.7 + 6.2x = 22.3
Solving
3.7 + 6.2x = 22.3
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3.7' to each side of the equation.
3.7 + -3.7 + 6.2x = 22.3 + -3.7
Combine like terms: 3.7 + -3.7 = 0.0
0.0 + 6.2x = 22.3 + -3.7
6.2x = 22.3 + -3.7
Combine like terms: 22.3 + -3.7 = 18.6
6.2x = 18.6
Divide each side by '6.2'.
x = 3
Simplifying
x = 3

6.2x + 3.7 = 22.3
subtract 3.7 on both sides
6.2x = 18.6
divide both sides by 6.2
x = 18.6/6.2 = 3
alternatively (if you don't like dividing by fractions)
6.2x = 18.6
multiply both sides by 10
62x = 186
divide both sides by 62
x = 186/62 = 3

6.2x + 3.7 = 22.3
6.2x +3.7 - 3.7 = 22.3 - 3.7
6.2x = 18.6
6.2 x / 6.2 = 18.6 / 6.2
x = 3
