0.4x - 1.2 - 1.6 = 0.5x - 2.5
0.4x - 2.8 = 0.5x - 2.5
0.4x - 0.5x = -2.5 + 2.8
-0.1x = 0.3
x = 0.3 / -0.1
x = -3
Therefore, the solution to the equation is x = -3.
0.4x - 1.2 - 1.6 = 0.5x - 2.5
0.4x - 2.8 = 0.5x - 2.5
0.4x - 0.5x = -2.5 + 2.8
-0.1x = 0.3
x = 0.3 / -0.1
x = -3
Therefore, the solution to the equation is x = -3.
