Equation at the end of step 2:
24 84
(—— • x) - —— = 0

STEP 3:
Adding fractions which have a common denominator :
3.1 Adding fractions which have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
24x - (84) 24x - 84
—————————— = ————————
5 5
STEP 4:
Pulling out like terms :
4.1 Pull out like factors :
24x - 84 = 12 • (2x - 7)
Equation at the end of step 4:
12 • (2x - 7)
————————————— = 0
5
The equation now takes the shape :
12 • (2x-7) = 0
Equations which are never true:
5.2 Solve : 12 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
5.3 Solve : 2x-7 = 0
Add 7 to both sides of the equation :
2x = 7
Divide both sides of the equation by 2:
x = 7/2 = 3.500
x = 7/2 = 3.500
