Answer:
D)
Explanation:
y= -x+2
y= 3x -4
Multiply y= -x +2 by 3 so we get:
3y=-3x +6
y= 3x -4
Then, we can use elimination to cancel the x and get:
3y= 6
y= -4
Add the y together as well as the 6 and -4 to get:
4y= 2
Then we get y= 1/2
Plug y= 1/2 into y= 3x -4 to get:
1/2= 3x -4
Add 4 to both sides to get:
4+(1/2)= 3x
4.5=3x
x=1.5 or 3/2
Hope this helps. Sorry its long.
