Question

X + 20 + 10x = 20x + 9x

Answer 1

Simplifying

X + 20x + 10x = 20 + 9x

Combine like terms: 20x + 10x = 30x

X + 30x = 20 + 9x

Solving

X + 30x = 20 + 9x

Solving for variable 'X'.

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

Add '-30x' to each side of the equation.

X + 30x + -30x = 20 + 9x + -30x

Combine like terms: 30x + -30x = 0

X + 0 = 20 + 9x + -30x

X = 20 + 9x + -30x

Combine like terms: 9x + -30x = -21x

X = 20 + -21x

Simplifying

X = 20 + -21x
