Question

how to re arrange the following as y=mx+c
1. 1/x+5=2/y
2. 3/x=1/y

whpalmer4 · Answer

$$\frac1{x + 5} = \frac2y$$
Is that correct?  You really should either use the Equation editor or parentheses to make the meaning of your equations clear!

campbell_st · Answer

just cross multiply so the 1st equation becomes

$$y = 2(x + 5)$$

now just expand and simplify to the equation to be in the form of 

y = mx + c

same process for the 2nd equation.

1st question i understood but second one i just have no idea to solve it as y=mx+b

whpalmer4 · Answer

$$\frac3x=\frac1y$$Multiply both sides by $xy$ and you get
$$3y = x$$$$y=\frac x3$$

whpalmer4 · Answer

which is $$y=(\frac{1}3)x+b$$where $b=0$
