(7+7n)+(-2+8x)
= 7+7x-2+8x
= 5+15x
359 goes to 360
224 goes to 220
360-220=140
I moved the answer up one then down four the way I moved the original numbers, so 140 is actually down three of the actual answer which must be 143 then
Each person would get 1/5 beacuse you would have to divide 5 into 4.
