Answer:
x= 15
Explanation:
Solve for x:
x/3 - 5 + 171 = 171
Put each term in x/3 - 5 + 171 over the common denominator 3: x/3 - 5 + 171 = x/3 - 15/3 + 513/3:
x/3 - 15/3 + 513/3 = 171
x/3 - 15/3 + 513/3 = (x - 15 + 513)/3:
(x - 15 + 513)/3 = 171
Add like terms. 513 - 15 = 498:
(x + 498)/3 = 171
Multiply both sides of (x + 498)/3 = 171 by 3:
(3 (x + 498))/3 = 3×171
(3 (x + 498))/3 = 3/3×(x + 498) = x + 498:
x + 498 = 3×171
3×171 = 513:
x + 498 = 513
Subtract 498 from both sides:
x + (498 - 498) = 513 - 498
498 - 498 = 0:
x = 513 - 498
513 - 498 = 15:
Answer: x = 15
