Question 51852
Your son should take notes in class.

Solve for x:
{{{2(2x-5)-5 = 2x+7}}} Apply the disributive property to the left side by multiplying the inside of the parentheses by 2.
{{{(4x-10)-5 = 2x + 7}}} Simplify the left side.
{{{4x - 15 = 2x + 7}}} Subtract 2x from both sides of the equation.
{{{2x - 15 = 7}}} Add 15 to both sides.
{{{2x = 22}}} Finally, divide both sides by 2.
{{{x = 11}}}
