Equations:
We need to solve the following equation:
1/2 ( 2x + 6 ) = 3x + 13
To eliminate the denominator, multiply both sides by 2:
2* 1/2 ( 2x + 6 ) = 2* (3x + 13)
Operate:
2x + 6 = 6x + 26
Move x's to the left and numbers to the right
2x - 6x = 26 - 6
Simplifying:
-4x = 20
Solving:
x = 20 / (-4) = -5
x = -5
