How do i solve equations with fractions?

2y - 3/5 = 1/2

2y = 1/2 + 3/5

2y = 5/10 + 6/10

Add the two fractions.

2y = 11/10

Divide both sides by 2.

y = 11/20

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
