Answer:
x = 73/4
Step-by-step explanation:
Solve for x:
12 x - 39 = 180
Add 39 to both sides:
12 x + (39 - 39) = 39 + 180
39 - 39 = 0:
12 x = 180 + 39
180 + 39 = 219:
12 x = 219
Divide both sides of 12 x = 219 by 12:
(12 x)/12 = 219/12
12/12 = 1:
x = 219/12
The gcd of 219 and 12 is 3, so 219/12 = (3×73)/(3×4) = 3/3×73/4 = 73/4:
Answer: x = 73/4
