8r + -8rs + 2s + 3s + 3t + -1t = 0

Combine like terms: 2s + 3s = 5s
8r + -8rs + 5s + 3t + -1t = 0

Combine like terms: 3t + -1t = 2t
8r + -8rs + 5s + 2t = 0

Solving
8r + -8rs + 5s + 2t = 0

Solving for variable 'r'.

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

Add '-5s' to each side of the equation.
8r + -8rs + 5s + -5s + 2t = 0 + -5s

Combine like terms: 5s + -5s = 0
8r + -8rs + 0 + 2t = 0 + -5s
8r + -8rs + 2t = 0 + -5s
Remove the zero:
8r + -8rs + 2t = -5s

Add '-2t' to each side of the equation.
8r + -8rs + 2t + -2t = -5s + -2t

Combine like terms: 2t + -2t = 0
8r + -8rs + 0 = -5s + -2t
8r + -8rs = -5s + -2t

Reorder the terms:
8r + -8rs + 5s + 2t = -5s + 5s + -2t + 2t

Combine like terms: -5s + 5s = 0
8r + -8rs + 5s + 2t = 0 + -2t + 2t
8r + -8rs + 5s + 2t = -2t + 2t

Combine like terms: -2t + 2t = 0
8r + -8rs + 5s + 2t = 0
