Answer:
x=-1, y=3
Step-by-step explanation:
3x+2y=3
3x-2y=-9
since we have -2y and 2y we can just add the equations
6x=-6
x+0y=-1
x=-1
to solve x using elimination multiply the top equation by -1
-3x-2y= -3
3x-2y=-9
and add
0x-4y=-12
-4y=-12
y=3
and substitute x and y to double; check
3(-1)+2(3)=3
-3+6=3
3=3
checks out so these are correct

Substitute the y=1:
2x + 5(1) = 9
2x + 5 = 5
subtract the 5:
2x = 4
Divide by 2:
x = 2
Answer:
x-int. = 4, if the equation is written correctly
Step-by-step explanation:
To find x- intercept y should be =0,
y = 0
y=3/2x-6
0= 3/2x - 6
6 *2/3= 3/2 x* 2/3
4 = x
x- int = 4
