Answer:

x= 35

Explanation:

5(x+20)=7x+30

Distribute 5 through the parenthesis

5x+100=7x+30

Move the variable sign to the left side and change its sign.

5x-7x+100=30

Move the constant to the right side and change its sign.

5x-7x=30-100

Collect like terms.

-2x=-70

Divide both sides of the equation by -2

x=35
