How To: Solving for "x" using multiplication and division

Solving for "x" using multiplication and division

Solving for "x" using multiplication and divisionHere is a typical algebraic equation "2x=12". Multiplication in algebra will have the "x" next to a number. The process will be a combination of multiplication and division to solve for "x". To get "x" alone, we do the opposite operation. 2x/2=12/2. Bring down the "=". You must balance the equation to make sure you did the computation correctly. 2x6=12. Next, we have a multiplication and addition problem. 4x+7=15. We must get rid of the 7. +7-7 on both sides of the equation. The "7" is cancelled. Bring down 4x=8. 4x/4=8/4. "x"=2. Check the answer to make sure it's balanced. 4x2+7=15. Do the multiplication first and then the addition.
