Question 189198: "If 3x+7=8 then what is the value of 2x-3?"
I tried to figure out what x is by multipling different numbers by 3 but I just cant seem to get it. I'm guessing that its probably a decimal but I dont know how to find/solve it correctly. Please help.

3x+7=8 then what is the value of 2x-3
-------------------
3x + 7 = 8
3x = 1
x = 1/3
---
2x = 2/3
2x-3 = (2/3) - (9/3)
2x - 3 = -7/3
