Answer:

x=16

Explanation:

Simplifying

0.4x + -4 = 2.4

Reorder the terms:

-4 + 0.4x = 2.4

Solving

-4 + 0.4x = 2.4

Solving for variable 'x'.

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

Add '4' to each side of the equation.

-4 + 4 + 0.4x = 2.4 + 4

Combine like terms: -4 + 4 = 0

0 + 0.4x = 2.4 + 4

0.4x = 2.4 + 4

Combine like terms: 2.4 + 4 = 6.4

0.4x = 6.4

Divide each side by '0.4'.

x = 16

Simplifying

x = 16
