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

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.

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

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