Answer:
Step-by-step explanation:
Bringing like terms on one side
4x - x = 7 + 1/2
3x = 7.5
x = 7.5/3
x = 2.5
X=5/2
1. subtract x from both sides, you now have 3x - 1/2 = 7
2. now you add 1/2 to both sides to get x by itself and you are left with 3x=7
4. divide by 3 on both sides to get x by itself
5. x=5/2
