X = 3y - 6....so sub 3y - 6 in for x in the other equation
2(3y - 6) - 4y = 8
6y - 12 - 4y = 8
2y = 8 + 12
2y = 20
y = 20/2
y = 10
x = 3y - 6
x = 3(10) - 6
x = 30 - 6
x = 24
solution is (24,10)
The only solution is (-3/2, 4)

Answer:
-2x+5y should be the answer
hope that helps
Enrolement increased by 30% that means last year=100%
incease of 30%=30+100=130% now
now=182
percent means parts out of 100 so
130%=130/100=13/10
182=13/10 of x (x represents the number last year)
of means multipy so
182=13/10 times x
multiply both sides by 10/13 to clear fraction
182 times 10/13=x=140
140 students last year
