Solution for 7v-4(v-9)=4(5v+9) equation:


Simplifying
7v + -4(v + -9) = 4(5v + 9)

Reorder the terms:
7v + -4(-9 + v) = 4(5v + 9)
7v + (-9 * -4 + v * -4) = 4(5v + 9)
7v + (36 + -4v) = 4(5v + 9)

Reorder the terms:
36 + 7v + -4v = 4(5v + 9)

Combine like terms: 7v + -4v = 3v
36 + 3v = 4(5v + 9)

Reorder the terms:
36 + 3v = 4(9 + 5v)
36 + 3v = (9 * 4 + 5v * 4)
36 + 3v = (36 + 20v)

Add '-36' to each side of the equation.
36 + -36 + 3v = 36 + -36 + 20v

Combine like terms: 36 + -36 = 0
0 + 3v = 36 + -36 + 20v
3v = 36 + -36 + 20v

Combine like terms: 36 + -36 = 0
3v = 0 + 20v
3v = 20v

Solving
3v = 20v

Solving for variable 'v'.

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