Isolate x. First, add 2/5 to both sides
x - 2/5 (+2/5) = 1/3 (+2/5)
x = 1/3 + 2/5
to simplify, find common denominators (15 in this case). Multiply the same number to both the denominator and numerator
(1/3)(5/5) = 5/15
(2/5)(3/3) = 6/15
x = 5/15 + 6/15
Simplify
x = 11/15
11/15 is your answer for x
hope this helps
