Question

100 + 2x × 100/40 = 5x + 4
​

Answer 1

Answer:

Simplifying

100 = (2x + 40)

Reorder the terms:

100 = (40 + 2x)

Remove parenthesis around (40 + 2x)

100 = 40 + 2x

Solving

100 = 40 + 2x

Solving for variable 'x'.

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

Add '-2x' to each side of the equation.

100 + -2x = 40 + 2x + -2x

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

100 + -2x = 40 + 0

100 + -2x = 40

Add '-100' to each side of the equation.

100 + -100 + -2x = 40 + -100

Combine like terms: 100 + -100 = 0

0 + -2x = 40 + -100

-2x = 40 + -100

Combine like terms: 40 + -100 = -60

-2x = -60

Divide each side by '-2'.

x = 30

Simplifying

x = 30
