Question may be :-
1) (20 - x) / 3 = x / 2
or
2) 20 - x/3 = x/2
Question 1
2(20 - x) = 3x
40 - 2x = 3x
40 = 5x
x = 8
Question 2
20 - x/3 = x/2
120 - 2x = 3x
5x = 120
x = 24
Tip
Make questions clear by using brackets.

20 - (x/3) = x/2
x/3 + x/2 = 20
6(x/3 + x/2) = 6(20)
2x + 3x = 120
5x = 120
x = 120/5
x = 24

20= x/2 +x/3.
20= 5x/6. x=24.

20- x/3 = x/2
Put the x's on the same side.
20 = x/3 + x/2
Make the denominators equal.
20 = 2x/6 + 3x/6
Add the numerators.
20 = 5x/6
Multiply both sides by six.
120 = 5x
Divide by 5.
x = 24
I think thats right

20 - (x/3) = (x/2)
40 - (2x/3) = x
40 - x = (2x/3)
2x = 120 - 3x
5x = 120
x = 24

20 - (x/3) = (x/2)
40 - (2x/3) = x
40 - x = (2x/3)
2x = 120 - 3x
5x = 120
x = 24
