Answer:

1/3 x = x - 22 is the answer I think.

Explanation:

You have to read this one step at a time.

1/3 x That's one third of a number

= equals

x - 22 the number minus 22

1/3 x = x - 22

============

Just because it is there, I'll solve it.

multiply both sides by 3

3*(1/3)x = 3(x - 22)

Remove the brackets on the right. show the multiplication on the left.

x = 3x - 66

Add 66 to both sides.

x + 66 = 3x - 66 + 66

x + 66 = 3x

Subtract x from both sides.

x - x + 66 = 3x - x

66 = 2x

Divide by 2

66/2 = 2x/2

x = 33
