Answer:

a. 2.5

b. 2.333

c. 2.85

Explanation:

A) 1. subtract -x on both sides 2. to get 3x-1/2=7

3. Add 1/2 on both sides 4. to get 3x=7.5

5. divide 3 on both sides 6. To get... x=2.5

B)1. Same process. 2. x+2=13/3

3. x=13/3-2 4. x= 2.33(repeating)

C) 1. same process. 2. 2x-x/3=3+7/4

3. 2x-x/3=4.75 4. Isolate -x/3

5.-x/3=4.75-2x 6. multiply both sides by 3

7. -x=14.25-6x 8. 5x=14.25

9. x= 2.85

* remember to distribute the 3 to each variable.
