Question

x+5+2x+10=30
Then x is ???

Answer 1

Answer:

Simplifying

5(2x + -10) = 30

Reorder the terms:

5(-10 + 2x) = 30

(-10 * 5 + 2x * 5) = 30

(-50 + 10x) = 30

Solving

-50 + 10x = 30

Solving for variable 'x'.

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

Add '50' to each side of the equation.

-50 + 50 + 10x = 30 + 50

Combine like terms: -50 + 50 = 0

0 + 10x = 30 + 50

10x = 30 + 50

Combine like terms: 30 + 50 = 80

10x = 80

Divide each side by '10'.

x = 8

Simplifying

x = 8
