Answer 2

Respuesta:

la X  es igual a 30 y la equacion es 580

Explicación:

Simplifying

5x + -40 = 3x + 20

Reorder the terms:

-40 + 5x = 3x + 20

Reorder the terms:

-40 + 5x = 20 + 3x

Solving

-40 + 5x = 20 + 3x

Solving for variable 'x'.

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

Add '-3x' to each side of the equation.

-40 + 5x + -3x = 20 + 3x + -3x

Combine like terms: 5x + -3x = 2x

-40 + 2x = 20 + 3x + -3x

Combine like terms: 3x + -3x = 0

-40 + 2x = 20 + 0

-40 + 2x = 20

Add '40' to each side of the equation.

-40 + 40 + 2x = 20 + 40

Combine like terms: -40 + 40 = 0

0 + 2x = 20 + 40

2x = 20 + 40

Combine like terms: 20 + 40 = 60

2x = 60

Divide each side by '2'.

x = 30

Simplifying

x = 30
