Question

Solve the equation..​

Answer 1

y=252/5=50.4

Explanation:

`(A)\ 9y-252=4y\\(B)\ 5y=252\\(C)\ y= \frac{252}5 = 50.4`

In step A we multiplied both sides by the least common multiple of the denominators, in order to deal with only integers for as long as possible.

In step B you subtract 4y and add 252 to both sides ("moving them on the other end of the equal sign").

In step C you finally divide by 5 to isolate y.
