Answer: X=  -4.8

Step-by-step explanation:Simplifying

0.8 + x = -4

Solving

0.8 + x = -4

Solving for variable 'x'.

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

Add '-0.8' to each side of the equation.

0.8 + -0.8 + x = -4 + -0.8

Combine like terms: 0.8 + -0.8 = 0

0 + x = -4 + -0.8

x = -4 + -0.8

Combine like terms: -4 + -0.8 = -4.8

x = -4.8

Simplifying

x = -4.8
