Answer:
It should be x-3/2 (also written as "(x-3)÷2")
Explanation:
y=2x+3
switch the y and x
x=2y+3
solve for y
x/2=y+3
x-3/2=y
If you graph these two functions you will see that y=2x+3 give the points (-1.5,0) and (0,3) and x-3/2 give (0,-1.5) and (3,0). because you've switched the x number to the y number you've "inversed" it
