Answer:
2x^2+4x-30=0
Step-by-step explanation:
2x^2+10x-6x-30=0
2x(x+5)-6(x+5)=0
(2x-6)(x+5)=0
2x-6=0 x+5=0
x=6/2 x=-5
x=3
Answer:
5x-2y=3
-3x+4y=1
5x-2y=-3x+4y+2
+2y
5x=-3x+6y+2
+3x
8x=6y+2
divide by 2
4x=3y+1
-3y+4x=1
wait so that means that -3x+4y=-3y+4x so that means that both x and y are equal so lets just say their the same
-3x+4x=1
x=1
y=1
