Question

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

Answer 1

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

Answer 2

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.

Answer 3

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

Answer 4

\[\frac3x=\frac1y\]Multiply both sides by \(xy\) and you get
\[3y = x\]\[y=\frac x3\]

Answer 5

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