x=4.2

Step-by-step explanation:
you add 2x to both sides to get rid of it on one side, do the same thing with the 2.4, so 5x=21 then divide both sides by 5 then you get x by itself and x=4.2
Hope this helps!! :)

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
