you could first multiply both sides by 4 to et rid of the fraction

Answer 2

*get

Answer 3

\[4(\frac{y}{-4}+5)=4*15\]

-y + 20 = 60
-y = 40
y = -40

do you understand?

Answer 7

Its quite easy, you have to get used to fractions in equations. In higher classes, you will have to face much tougher equations with decimals too.
