Question

no one can get the right answer..ive been wrong 3 times.. help please

solve (1)symbolically (2) numerically
6x+3y= 6 -6x+2y=-6

Answer 1

3y=6-6x
y=2(1-x)

Answer 2

for the first equation divide by 3 so you get 2x + y = 6, so then y = -2x + 6
and x = (-y+6)/2 this is symbolic

Answer 3

-6x+2(2(1-x))=-6
-10x+4=-6
-10x=-10
x=1

Answer 4

then sub x=1 into an equation
