Answer:
x=16
Step-by-step 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
