-9/4

Step-by-step explanation:

First you subtract 7/2 from both sides of the equation

3x + 7/2 - 7/2= x - 1 - 7/2

Next what you do is simplify one you add 3 + 7/2 which is 9/2

Then you subtract X from both sides of the equation

3x - x = x - 9/2 - x

combine the terms

2x = -9/2

divide both sides of the equation by the same term

2x/2 = 9/2 / 2

cancel the terms and divide the numbers

x=-9/4
