Solution for 10r-3s-(r-2s)-(-3s+5t)= equation:


Simplifying
10r + -3s + -1(r + -2s) + -1(-3s + 5t) = 0
10r + -3s + (r * -1 + -2s * -1) + -1(-3s + 5t) = 0
10r + -3s + (-1r + 2s) + -1(-3s + 5t) = 0
10r + -3s + -1r + 2s + (-3s * -1 + 5t * -1) = 0
10r + -3s + -1r + 2s + (3s + -5t) = 0

Reorder the terms:
10r + -1r + -3s + 2s + 3s + -5t = 0

Combine like terms: 10r + -1r = 9r
9r + -3s + 2s + 3s + -5t = 0

Combine like terms: -3s + 2s = -1s
9r + -1s + 3s + -5t = 0

Combine like terms: -1s + 3s = 2s
9r + 2s + -5t = 0

Solving
9r + 2s + -5t = 0

Solving for variable 'r'.

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

Add '-2s' to each side of the equation.
9r + 2s + -2s + -5t = 0 + -2s

Combine like terms: 2s + -2s = 0
9r + 0 + -5t = 0 + -2s
9r + -5t = 0 + -2s
Remove the zero:
9r + -5t = -2s

Add '5t' to each side of the equation.
9r + -5t + 5t = -2s + 5t

Combine like terms: -5t + 5t = 0
9r + 0 = -2s + 5t
9r = -2s + 5t

Divide each side by '9'.
r = -0.2222222222s + 0.5555555556t

Simplifying
r = -0.2222222222s + 0.5555555556t
