Question

solve 10x - 40 = 5x + 25​

Answer 1

Step-by-step explanation:

Simplifying

10x + -40 = 5x + 25

Reorder the terms:

-40 + 10x = 5x + 25

Reorder the terms:

-40 + 10x = 25 + 5x

Solving

-40 + 10x = 25 + 5x

Solving for variable 'x'.

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

Add '-5x' to each side of the equation.

-40 + 10x + -5x = 25 + 5x + -5x

Combine like terms: 10x + -5x = 5x

-40 + 5x = 25 + 5x + -5x

Combine like terms: 5x + -5x = 0

-40 + 5x = 25 + 0

-40 + 5x = 25

Add '40' to each side of the equation.

-40 + 40 + 5x = 25 + 40

Combine like terms: -40 + 40 = 0

0 + 5x = 25 + 40

5x = 25 + 40

Combine like terms: 25 + 40 = 65

5x = 65

Divide each side by '5'.

x = 13

Simplifying

x = 13

Answer 2
