x + 3/5 = 1 2/5

x = 1 2/5 - 3/5
x = 7/5 - 3/5
x = ?

I don't understand

ok thanks I got it now

Great!

To solve the equation x + 3/5 = 1 2/5, we need to isolate the variable x.

Step 1: Let's rewrite the mixed numbers as improper fractions.
1 2/5 = (5 * 1 + 2) / 5 = 7/5

Step 2: Subtract 3/5 from both sides of the equation to eliminate the fraction on the left side.

x + 3/5 - 3/5 = 7/5 - 3/5

On the left side, the 3/5 terms cancel out, leaving us with:

x = 7/5 - 3/5

Step 3: Subtract the fractions on the right side.

x = (7 - 3) / 5

Simplifying further:

x = 4/5

So the solution to the equation x + 3/5 = 1 2/5 is x = 4/5.
