Solve for x:
x-5/4 = 7
Put each term in x-5/4 over the common denominator 4: x-5/4 = (4 x)/4-(5)/4:
(4 x)/4-(5)/4 = 7
(4 x)/4-(5)/4 = (4 x-5)/4:
(4 x-5)/4 = 7
Multiply both sides of (4 x-5)/4 = 7 by 4:
(4 (4 x-5))/4 = 4×7
(4 (4 x-5))/4 = 4/4×(4 x-5) = 4 x-5:
4 x-5 = 4×7
4×7 = 28:
4 x-5 = 28
Add 5 to both sides:
4 x+(5-5) = 28+5
5-5 = 0:
4 x = 28+5
28+5 = 33:
4 x = 33
Divide both sides of 4 x = 33 by 4:
(4 x)/4 = 33/4
4/4 = 1:
Answer: | x = 33/4
