Question

Five' more than twice a
number is -13. Find the
number

Answer 1

Answer:

-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

Answer 2

Answer:

the number is -9

2 x -9 = -18

5 + -18 = -13
