2.2(y+15)=-0.3(y-18)

Solution for 2.2(y+15)=-0.3(y-18) equation:

Simplifying
2.2(y + 15) = -0.3(y + -18)

Reorder the terms:
2.2(15 + y) = -0.3(y + -18)
(15 * 2.2 + y * 2.2) = -0.3(y + -18)
(33 + 2.2y) = -0.3(y + -18)

Reorder the terms:
33 + 2.2y = -0.3(-18 + y)
33 + 2.2y = (-18 * -0.3 + y * -0.3)
33 + 2.2y = (5.4 + -0.3y)

Solving
33 + 2.2y = 5.4 + -0.3y

Solving for variable 'y'.

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

Add '0.3y' to each side of the equation.
33 + 2.2y + 0.3y = 5.4 + -0.3y + 0.3y

Combine like terms: 2.2y + 0.3y = 2.5y
33 + 2.5y = 5.4 + -0.3y + 0.3y

Combine like terms: -0.3y + 0.3y = 0.0
33 + 2.5y = 5.4 + 0.0
33 + 2.5y = 5.4

Add '-33' to each side of the equation.
33 + -33 + 2.5y = 5.4 + -33

Combine like terms: 33 + -33 = 0
0 + 2.5y = 5.4 + -33
2.5y = 5.4 + -33

Combine like terms: 5.4 + -33 = -27.6
2.5y = -27.6

Divide each side by '2.5'.
y = -11.04

Simplifying
y = -11.04
