When three times a number is increased by 2, the result is 17. Find the number

Question

translate each into an equation then solve 

Answer 1

Three times a number: 3*x

 

Increased by 2: +2

 

Result is 17: =17

 

Therefore your equation is 3*x+2=17, where x is "a number". To solve this equation, you will need to use math operations on each side to have x="your answer".

 

Subtract 2 to both sides: (3*x+2)-2=(17)-2    ---> 3*x=15

 

Divide both sides by 3: (3*x)/3=(15)/3     ---> x=5

 

Therefore, your answer is x=5.
