Basic algebraic operations; you need to learn them....

4x-2%28x%2B3%29=8

Use the distributive property to get rid of the parentheses. Remember BOTH terms inside the parentheses are multiplied by NEGATIVE 2.

4x-2x-6+=+8

Get all the terms containing the variable on one side and all the other terms on the other side.

4x-2x+=+8%2B6

Combine like terms on both sides.

2x+=+14

Divide by 2 to get "x" by itself.

x+=+7

ANSWER: x=7

Especially when you are just learning algebra, you should check your answer in the original equation.

4(7)-2(7+3) = 28-2(10) = 28-20 = 8 YES!
