Answer:
x=5
y=-1
Step-by-step explanation:
-2x+3-7y=0 equation 1
-15+5x=-10y equation 2
using equation 2 we have:
-15+5x=-10y
5x = -10y +15
x = -2y +3 equation 3
using equation 3 in equation 1 we have:
-2(-2y+3)+3-7y=0
4y -6 +3 -7y=0
-3y -3= 0
3y= -3
y= -3/3
y = -1
so we have:
x = -2y +3
x = -2(-1) +3
x = 2+3
x =5
