Solution for 3(v+2)+4=5(v-1)+u equation: 


Simplifying
3(v + 2) + 4 = 5(v + -1) + u

Reorder the terms:
3(2 + v) + 4 = 5(v + -1) + u
(2 * 3 + v * 3) + 4 = 5(v + -1) + u
(6 + 3v) + 4 = 5(v + -1) + u

Reorder the terms:
6 + 4 + 3v = 5(v + -1) + u

Combine like terms: 6 + 4 = 10
10 + 3v = 5(v + -1) + u

Reorder the terms:
10 + 3v = 5(-1 + v) + u
10 + 3v = (-1 * 5 + v * 5) + u
10 + 3v = (-5 + 5v) + u

Reorder the terms:
10 + 3v = -5 + u + 5v

Solving
10 + 3v = -5 + u + 5v

Solving for variable 'v'.

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

Add '-5v' to each side of the equation.
10 + 3v + -5v = -5 + u + 5v + -5v

Combine like terms: 3v + -5v = -2v
10 + -2v = -5 + u + 5v + -5v

Combine like terms: 5v + -5v = 0
10 + -2v = -5 + u + 0
10 + -2v = -5 + u

Add '-10' to each side of the equation.
10 + -10 + -2v = -5 + -10 + u

Combine like terms: 10 + -10 = 0
0 + -2v = -5 + -10 + u
-2v = -5 + -10 + u

Combine like terms: -5 + -10 = -15
-2v = -15 + u

Divide each side by '-2'.
v = 7.5 + -0.5u

Simplifying
v = 7.5 + -0.5u
