Answer:
Step-by-step explanation:
7x-2y=5xy
8x+7y=15xy
multiply the first equation by 3
21x-6y=15xy=8x+7y
13x-13y=0
x-y=0
x=y
therefore substituting in the first equation
7x-2x=5x^2
5x^2=5x
x=0
or x=+1
but x=y we have already established that so
y=0
or
y=+1
but if we look at the original form x=0 or y=0 wont work
x=1 and y=1
