-1.5(y-1.5)=-1.2(y-.5)

Solution for -1.5(y-1.5)=-1.2(y-.5) equation:

Simplifying
-1.5(y + -1.5) = -1.2(y + -0.5)

Reorder the terms:
-1.5(-1.5 + y) = -1.2(y + -0.5)
(-1.5 * -1.5 + y * -1.5) = -1.2(y + -0.5)
(2.25 + -1.5y) = -1.2(y + -0.5)

Reorder the terms:
2.25 + -1.5y = -1.2(-0.5 + y)
2.25 + -1.5y = (-0.5 * -1.2 + y * -1.2)
2.25 + -1.5y = (0.6 + -1.2y)

Solving
2.25 + -1.5y = 0.6 + -1.2y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '1.2y' to each side of the equation.
2.25 + -1.5y + 1.2y = 0.6 + -1.2y + 1.2y

Combine like terms: -1.5y + 1.2y = -0.3y
2.25 + -0.3y = 0.6 + -1.2y + 1.2y

Combine like terms: -1.2y + 1.2y = 0.0
2.25 + -0.3y = 0.6 + 0.0
2.25 + -0.3y = 0.6

Add '-2.25' to each side of the equation.
2.25 + -2.25 + -0.3y = 0.6 + -2.25

Combine like terms: 2.25 + -2.25 = 0.00
0.00 + -0.3y = 0.6 + -2.25
-0.3y = 0.6 + -2.25

Combine like terms: 0.6 + -2.25 = -1.65
-0.3y = -1.65

Divide each side by '-0.3'.
y = 5.5

Simplifying
y = 5.5
