Answer:
x = 4.2
Step-by-step explanation:
Simplifying
18.6 + -2x = 3x + -2.4
Reorder the terms:
18.6 + -2x = -2.4 + 3x
Solving
18.6 + -2x = -2.4 + 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.
18.6 + -2x + -3x = -2.4 + 3x + -3x
Combine like terms: -2x + -3x = -5x
18.6 + -5x = -2.4 + 3x + -3x
Combine like terms: 3x + -3x = 0
18.6 + -5x = -2.4 + 0
18.6 + -5x = -2.4
Add '-18.6' to each side of the equation.
18.6 + -18.6 + -5x = -2.4 + -18.6
Combine like terms: 18.6 + -18.6 = 0.0
0.0 + -5x = -2.4 + -18.6
-5x = -2.4 + -18.6
Combine like terms: -2.4 + -18.6 = -21
-5x = -21
Divide each side by '-5'.
x = 4.2
Simplifying
x = 4.2
