Solution for 5(u+1)=90-4(10-u) equation:


Simplifying
5(u + 1) = 90 + -4(10 + -1u)

Reorder the terms:
5(1 + u) = 90 + -4(10 + -1u)
(1 * 5 + u * 5) = 90 + -4(10 + -1u)
(5 + 5u) = 90 + -4(10 + -1u)
5 + 5u = 90 + (10 * -4 + -1u * -4)
5 + 5u = 90 + (-40 + 4u)

Combine like terms: 90 + -40 = 50
5 + 5u = 50 + 4u

Solving
5 + 5u = 50 + 4u

Solving for variable 'u'.

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

Add '-4u' to each side of the equation.
5 + 5u + -4u = 50 + 4u + -4u

Combine like terms: 5u + -4u = 1u
5 + 1u = 50 + 4u + -4u

Combine like terms: 4u + -4u = 0
5 + 1u = 50 + 0
5 + 1u = 50

Add '-5' to each side of the equation.
5 + -5 + 1u = 50 + -5

Combine like terms: 5 + -5 = 0
0 + 1u = 50 + -5
1u = 50 + -5

Combine like terms: 50 + -5 = 45
