Y = x - 1
-x + 3/2 = -y

It has more than one equal sign but set up like this:

Step-by-step explanation:

Let's solve for x.

y+x−1+

3

2

=−y

Step 1: Add -y to both sides.

x+y+

1

2

+−y=−y+−y

x+

1

2

=−2y

Step 2: Add (-1)/2 to both sides.

x+

1

2

+

−1

2

=−2y+

−1

2

x=−2y+

−1

2

x=−2y+ -1/2
