Question

Joe has 4 less than 7 times as many shirts as Mark. Together, Joe and Mark have 140 shirts. How many shirts does Joe have? How many shirts docs Mark have?​

Answer 1

Mark has 18 shirts

Given that together they have 140 shirts.

x + 7x - 4 = 140

8x = 140 + 4

8x = 144

x = 144/8

x = 18

Joe has 122 shirts

7x - 4

7 × 18 - 4

126 - 4

= 122
