Solve:
5(20-x)=1/2(4x+4)
Distribute 5 to 20 and -x, and 1/2 to 4x and 4
5(20) = 100
5(-x) = -5x
4x/2 = 2x
4/2 = 2
Simplify
-5x + 100 = 2x + 2
Isolate the x. Subtract 2x from both sides, and 100 from both sides
-5x (-2x) + 100 (-100) = 2x (-2x) + 2 (-100)
-5x - 2x = 2 - 100
Simplify
-7x = -98
Isolate the x. Divide -7 from both sides
-7x/-7 = -98/-7
x = -98/-7
x = 14
14 is your answer for x
hope this helps
