Answer:

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

Which of the following values of x makes the rational expression below undefined? x-25/x+13
san4es73 [151]
X-25 / x + 13
 For this case what you should know is that an indefinite expression are those in which mathematically no numerical value can be obtained.
 We have then that a division between zero causes an expression to be undefined.
 For x = -13 we have:
 (-13-25) / (- 13 + 13) = - 38/0 (undefined)
 Answer:
 x = -13
 d. -13
