what is the solution of the system y=10x-2 y=-7x+4
A(5/17,16/17)this is the right answer
B(4/17,16/19)
C(-5/17,16/17)
D(3/17,5/17)

Respuesta :

Y=10x-2 Y=-7x+4

-7x+4=10x-2
+7x +7x
4=17x-2
+2 +2
6=17x
6/17=17x/17
(6/17)=x

Y=10(6/17)-2
Y=(60/17)-2
Y=3(9/17)-2
Y=1(9/17)

I got a different answer would you like to explain, b/c I'm confuse now☺️.
