A: 0.25[2.5x + 1.5(x – 4)] = –x.

x = 0.75

Multiply both sides by 4

2.5x +1.5(x - 4) = -4x

Multiply the bracketed term by 1.5

2.5x + 1.5x - 1.5*4 = -4x

Simplify the left-hand side

4x - 6 = -4x

Add 4x to both sides

8x - 6 = 0

Add 6 to both sides

8x = 6

Divide both sides by 8

x = 6/8

Simplify

x = 3/4 (or x = 0.75)
