Answer:

The number is 17

Step-by-step explanation:

Let the number be n. Increasing this by 30 results in n + 30. Tripling this result results in 3(n + 30) = 141.

Multiplying as indicated: 3n + 90 = 141, or

3n = 51

Solving for n, we get n = 51/3 = 17

Answer:

The original number is 17.

Step-by-step explanation:

$3(x+30)=141\\\\\frac{3(x+30)}{3}=\frac{141}{3}\\\\x+30=47\\\\x+30-30=47-30\\\\x=17$
