This would just be 7 1/5 + 3/5 since the negative sign gets distributed and makes (-3/5) into a positive number.
From there you have basic math and you get 7 4/5.
$22000-$13200=$8800
$22000=100%
1%=$22000÷1000%
=$220
$8800÷$220=40
The percentage decrease is 40%.
1st system: 2x = 14 <=> x = 7
2nd system: 2x = 4 <=> x = 2
