A man has x matches in a matchbox. On

Monday he uses one-quarter of the matches

On Tuesday he uses five more. How many

matches has he used? How many has he left?

Used: 1/4x + 5

Left: 3/4x - 5

Step-by-step explanation:

Monday: 1/4 of the x matched

1/4x are used

Tuesday: uses 5 more

1/4x + 5 are used

Total used 1/4x + 5

To find what is left, take what was started with x, and subtract what was used

Left: x - (1/4x+5)

x - 1/4x - 5

3/4x - 5
