Solution for 5x=(4x+3)(m+7) equation:


Simplifying
5x = (4x + 3)(m + 7)

Reorder the terms:
5x = (3 + 4x)(m + 7)

Reorder the terms:
5x = (3 + 4x)(7 + m)

Multiply (3 + 4x) * (7 + m)
5x = (3(7 + m) + 4x * (7 + m))
5x = ((7 * 3 + m * 3) + 4x * (7 + m))
5x = ((21 + 3m) + 4x * (7 + m))
5x = (21 + 3m + (7 * 4x + m * 4x))

Reorder the terms:
5x = (21 + 3m + (4mx + 28x))
5x = (21 + 3m + (4mx + 28x))
5x = (21 + 3m + 4mx + 28x)

Solving
5x = 21 + 3m + 4mx + 28x

Solving for variable 'x'.

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

Add '-4mx' to each side of the equation.
-4mx + 5x = 21 + 3m + 4mx + -4mx + 28x

Combine like terms: 4mx + -4mx = 0
-4mx + 5x = 21 + 3m + 0 + 28x
-4mx + 5x = 21 + 3m + 28x

Add '-28x' to each side of the equation.
-4mx + 5x + -28x = 21 + 3m + 28x + -28x

Combine like terms: 5x + -28x = -23x
-4mx + -23x = 21 + 3m + 28x + -28x

Combine like terms: 28x + -28x = 0
-4mx + -23x = 21 + 3m + 0
-4mx + -23x = 21 + 3m

-21 + -3m + -4mx + -23x = 21 + 3m + -21 + -3m

Reorder the terms:
-21 + -3m + -4mx + -23x = 21 + -21 + 3m + -3m

Combine like terms: 21 + -21 = 0
-21 + -3m + -4mx + -23x = 0 + 3m + -3m
-21 + -3m + -4mx + -23x = 3m + -3m

Combine like terms: 3m + -3m = 0
-21 + -3m + -4mx + -23x = 0
