I’m not sure I’m reading the equation correctly from your formatting. Could you retype it more clearly? For example, is the problem
- (2/5) x − 1/5 = 1/20 or
- (3/5) x − 1/5 = 1/20 or something else?
If you’re solving for x, here’s how it works in those two cases:
If (2/5)x − 1/5 = 1/20
- Add 1/5 to both sides: (2/5)x = 1/20 + 1/5 = 1/20 + 4/20 = 5/20 = 1/4
- Multiply both sides by 5/2: x = (1/4) * (5/2) = 5/8
If (3/5)x − 1/5 = 1/20
- (3/5)x = 1/20 + 1/5 = 5/20 = 1/4
- x = (1/4) / (3/5) = (1/4) * (5/3) = 5/12
If it’s something else (e.g., a numeric check like sqrt(2/5) − 1/5 = 1/20), please confirm.
