Answer:
x = -1, y = 1
Step-by-step explanation:
2x-y=-3 // y = 2x + 3 (eqn 1)
3x+y=-2 (eqn 2)
sub 1 into 2
3x + 2x + 3 = -2
5x = -5
x = -1
sub x = -1 into eqn 1
y = -2+3
y = 1
Percent change=100 times change/original
change=original-new
change=90-84.50=5.5
percent change=100 times 5.5/90
percent change=550/90
percent change=6.11111
percent change=6.1%
