Solution for 42x+x=2x(8+x) equation:


Simplifying
42x + x = 2x(8 + x)

Combine like terms: 42x + x = 43x
43x = 2x(8 + x)
43x = (8 * 2x + x * 2x)
43x = (16x + 2x2)

Solving
43x = 16x + 2x2

Solving for variable 'x'.

Combine like terms: 43x + -16x = 27x
27x + -2x2 = 16x + 2x2 + -16x + -2x2

Reorder the terms:
27x + -2x2 = 16x + -16x + 2x2 + -2x2

Combine like terms: 16x + -16x = 0
27x + -2x2 = 0 + 2x2 + -2x2
27x + -2x2 = 2x2 + -2x2

Combine like terms: 2x2 + -2x2 = 0
27x + -2x2 = 0

Factor out the Greatest Common Factor (GCF), 'x'.
x(27 + -2x) = 0

Subproblem 1

Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0

Subproblem 2

Set the factor '(27 + -2x)' equal to zero and attempt to solve: Simplifying 27 + -2x = 0 Solving 27 + -2x = 0 Move all terms containing x to the left, all other terms to the right. Add '-27' to each side of the equation. 27 + -27 + -2x = 0 + -27 Combine like terms: 27 + -27 = 0 0 + -2x = 0 + -27 -2x = 0 + -27 Combine like terms: 0 + -27 = -27 -2x = -27 Divide each side by '-2'. x = 13.5 Simplifying x = 13.5

Solution

x = {0, 13.5}
