[latex]Simplifying -1.6x + 5 = 7.8 Reorder the terms: 5 + -1.6x = 7.8 Solving 5 + -1.6x = 7.8 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + -1.6x = 7.8 + -5 Combine like terms: 5 + -5 = 0 0 + -1.6x = 7.8 + -5 -1.6x = 7.8 + -5 Combine like terms: 7.8 + -5 = -12.8 -1.6x = 12.8 Divide each side by '1.6'. x = 8 Simplifying x = 8[/latex]
