x=5/6
y=3/2
Step-by-step explanation:
They are both equal to y so set them equal to each other. (transitive property)
3x-1=1/2x+2
Multiply each side by 2.
(2) (3x-1) = 2 (1/2x+2)
6x-2=x+4
Subtract x from each side.
5x-2=4
Add two to each side.
5x=6
Divide each side by 5.
x=5/6
Now plug 5/6 into y=3x-1.
y=3 (5/6) - 1
y = (15/6) - 1
y = (5/2) - 1
Subtract 1.
y=3/2
