Answer:
y=13/4
x=3/4
tell you teacher that problems like tis one should be
done with elimination method, only use substation is a variable is already isolated !
Step-by-step explanation:
~~~~~~~~~~~~
7/2 x -1 = y
3x= 2(7/2x-1) -1
3x = 7x-2 -1
3x = 7x -3
-4x = - 3
x = 3/4
y = 3(3/4)+1 = 9/4 + 4/4 = 13/4
