Hi!
First you need to put these in y=mx+b form.
 2x  5y = 16
 Subtract both sides by (2x), giving you 5y= 162x
 Divide by both sides by (5) to get y by itself, giving you y= (16/5) + (2/5)x
 4x  10y= 16
 Follow the same steps: first subtract by (4x), giving you 10y= 16  4x
 Divide both sides by (10) giving you, y= (16/10) + (4/10)x which can be simplified to y= (8/5) + (2/5)x
If solving for x and y then set both equations equal to each other since they are both equal to 16:
 2x5y = 4x 10y
 Combine like terms: add 10y to both sides giving you, 2x 5y = 4x
 subtract 2y from both sides giving you 5y = 2x
 Divide by 5, so now y= (2/5)x
 Now substitute one of the old equations in to receive what y is equal to
