Question

When a number is tripled, the result is 4 more than 11. What is the number ?

Answer 1

Answer:

Let n be the number. Two subtracted from the number would be n−2 . Tripling that gives 3(n−2) , and gives four more than the number, or n+4 .

3(n−2)=n+4

Distribute the 3 inside the parentheses:

3n−6=n+4

Subtract n from both sides:

2n−6=4

Add 6 to both sides:

2n=10

Divide both sides by 2; n=5 .

Answer 2

Step-by-step explanation:

let the tripled number be x

We get,

3x=4+11

3x=15

x=15

3

therefore,the number is 5
