Five' more than twice a

number is - 13. Find the

number

the number is - 9

2 x - 9 = - 18

5 + - 18 = - 13

-9

Step-by-step explanation:

n - a number

five more: + 5

twice a number: 2 · n = 2n

five more than twice a number: 2n + 5

The equation:

2n + 5 = - 13 subtract 5 from both sides

2n + 5 - 5 = - 13 - 5

2n = - 18 divide both sides by 2

2n/2 = - 18/2

n = - 9
