The teacher will be very surprised to see your correct solution 😉

You have entered [src]

3*y   29      
--- = -- - 1/5
 5    10

$$\frac{3 y}{5} = - \frac{1}{5} + \frac{29}{10}$$

Simplify

Detail solution

Given the linear equation:

3/5*y = 29/10-1/5

Looking for similar summands in the right part:

3*y/5 = 27/10

Divide both parts of the equation by 3/5

y = 27/10 / (3/5)

We get the answer: y = 9/2
