Question

Translate to an equation, then solve. Fifteen less than four times a number is equal to 11 more than two times the number.

Answer 1

see explanation

Explanation:

let the number be n then 15 less than 4 times the number is 4n - 15

and 11 more than 2 times the number is 2n + 11

then equate the 2 expressions

4n - 15 = 2n + 11

to solve subtract 2n from both sides

2n - 15 = 11 ( add 15 to both sides )

2n = 26 ( divide both sides by 2 )

n = 13

the number is 13
