1) Distributing the negative sign on the left side:
0.8 - 1.5x + 2 = -0.8 + 4.5x
2.8 - 1.5x = -0.8 + 4.5x

Bringing like terms together:
2.8 + 0.8 = 4.5x + 1.5x
3.6 = 6x

Dividing by 6 on both sides:
x = 0.6

2) Distributing on both sides:
0.6x - 1.5x - 1 = 0.5x - 0.5 - 0.8
-0.9x - 1 = 0.5x - 1.3

Bringing like terms together:
-0.9x - 0.5x = -1.3 + 1
-1.4x = -0.3

Dividing by -1.4 on both sides:
x ≈ 0.21428571429

Therefore, the solutions to the two equations are x = 0.6 and x ≈ 0.21428571429.
