1.7(y+18)=-1.7(y-5)

Solution for 1.7(y+18)=-1.7(y-5) equation:

Simplifying
1.7(y + 18) = -1.7(y + -5)

Reorder the terms:
1.7(18 + y) = -1.7(y + -5)
(18 * 1.7 + y * 1.7) = -1.7(y + -5)
(30.6 + 1.7y) = -1.7(y + -5)

Reorder the terms:
30.6 + 1.7y = -1.7(-5 + y)
30.6 + 1.7y = (-5 * -1.7 + y * -1.7)
30.6 + 1.7y = (8.5 + -1.7y)

Solving
30.6 + 1.7y = 8.5 + -1.7y

Solving for variable 'y'.

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

Add '1.7y' to each side of the equation.
30.6 + 1.7y + 1.7y = 8.5 + -1.7y + 1.7y

Combine like terms: 1.7y + 1.7y = 3.4y
30.6 + 3.4y = 8.5 + -1.7y + 1.7y

Combine like terms: -1.7y + 1.7y = 0.0
30.6 + 3.4y = 8.5 + 0.0
30.6 + 3.4y = 8.5

Add '-30.6' to each side of the equation.
30.6 + -30.6 + 3.4y = 8.5 + -30.6

Combine like terms: 30.6 + -30.6 = 0.0
0.0 + 3.4y = 8.5 + -30.6
3.4y = 8.5 + -30.6

Combine like terms: 8.5 + -30.6 = -22.1
3.4y = -22.1

Divide each side by '3.4'.
y = -6.5

Simplifying
y = -6.5
