3.6=0.72(y+6)

Solution for 3.6=0.72(y+6) equation:

Simplifying
3.6 = 0.72(y + 6)

Reorder the terms:
3.6 = 0.72(6 + y)
3.6 = (6 * 0.72 + y * 0.72)
3.6 = (4.32 + 0.72y)

Solving
3.6 = 4.32 + 0.72y

Solving for variable 'y'.

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

Add '-0.72y' to each side of the equation.
3.6 + -0.72y = 4.32 + 0.72y + -0.72y

Combine like terms: 0.72y + -0.72y = 0.00
3.6 + -0.72y = 4.32 + 0.00
3.6 + -0.72y = 4.32

Add '-3.6' to each side of the equation.
3.6 + -3.6 + -0.72y = 4.32 + -3.6

Combine like terms: 3.6 + -3.6 = 0.0
0.0 + -0.72y = 4.32 + -3.6
-0.72y = 4.32 + -3.6

Combine like terms: 4.32 + -3.6 = 0.72
-0.72y = 0.72

Divide each side by '-0.72'.
y = -1

Simplifying
y = -1
