Solution for 4+0.5(1-y)=1.8y-4(y-0.5) equation:


Simplifying
4 + 0.5(1 + -1y) = 1.8y + -4(y + -0.5)
4 + (1 * 0.5 + -1y * 0.5) = 1.8y + -4(y + -0.5)
4 + (0.5 + -0.5y) = 1.8y + -4(y + -0.5)

Combine like terms: 4 + 0.5 = 4.5
4.5 + -0.5y = 1.8y + -4(y + -0.5)

Reorder the terms:
4.5 + -0.5y = 1.8y + -4(-0.5 + y)
4.5 + -0.5y = 1.8y + (-0.5 * -4 + y * -4)
4.5 + -0.5y = 1.8y + (2 + -4y)

Reorder the terms:
4.5 + -0.5y = 2 + 1.8y + -4y
