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

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

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
