3y+x=4
2y-x=6
Solve x+3y=4 for x
Add -3y to both sides
x+3y-3y=4-3y
x=-3y+4
Substitute -3y+4 for x in -x+2y=6
-x+2y=6
-(-3y+4)+2y=6
Simplify both sides of the equation
5y-4=6
Add 4 to both sides
5y-4+4=6+4
5y=10
Divide both sides by 5
5y/5=10/5
y=2
Substitute 2 for y in x=-3y+4
x=-3y+4
x=(-3)(2)+4
x= -6+4
x= -2
Answer : x=-2 and y=2
The answer is A
it is (-2,2) and lies on both lines
I hope that's help !
