Answer:
(2,2)

Explanation:

1. Substitute
y=0 into first equation and solve for "x" in order to find the x-intercept of the first line:


0=-(1)/(2)x+3\\\\-3=-(1)/(2)x\\\\(-3)(-2)=x\\\\x=6

2. Substitute
x=0 into the first equation and solve for "y" in order to find the y-intercept of the first line:


y=-(1)/(2)(0)+3\\\\y=3

Knowing that first line passes through the points
(6,0) and
(0,3), you can graph it.

3. Substitute
y=0 into second equation and solve for "x" in order to find the x-intercept:


0=2x-2\\\\2=2x\\\\x=1

4. Substitute
x=0 into the second equation and solve for "y" in order to find the y-intercept of the second line:


y=2(0)-2\\\\y=-2

Knowing that second line passes through the points
(1,0) and
(0,-2), you can graph it.

The solution of the system of equations is the point of intersection between the lines. Therefore, the solution of this system is:


(2,2)
