What's 1/3x-5+171=171

x = 15

Step-by-step 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
