Answer:
Step-by-step explanation:
1st ) 1/3x + 2 = 7
Move 2 to other side.
1/3x = 5
Multiply each side by 3.
x = 15
That means it is a whole number not a fraction.
2nd ) 1/2x + 1/2 = 8/2
Move 1/2 to the other side.
1/2x = 8/2 - 1/2
1/2x = 7/2
Multiply each side by 2.
x = 14/2 = 7
That is a whole number.
3rd ) 3x + 2/3 = 5/3
Move 2/3 to the other side.
3x = 5/3 - 2/3
3x = 3/3 = 1
Divide each side by 3.
x = 1/3
That is a fraction.
