Question

Seven more than one–third of a number is 18. What is the number?

Answer 1

Let the number be x

-----------------------------------------
Interpret the statement
-----------------------------------------

`(1)/(3)x + 7 = 18`

-----------------------------------------
Solve x
-----------------------------------------

`(1)/(3)x + 7 - 7 = 18 - 7 \Longleftarrow {\text {minus 7 from both size}`


`(1)/(3)x = 11`


`(1)/(3)x * 3 = 11 * 3 \Longleftarrow {\text {multiply by 3 on both side}`


`x = 33`

-----------------------------------------
Answer: x = 33
