Question

If (x+2)/2 = y/5, then which of the following must be true?


x/2 = (y-2)/5
x/2 = (y-5)/5
(x+2)/5 = y/25

Answer 1

you could use algebra to see if you can re-arrange the equation to get one of the choices.

you could also test (x,y) pairs and see if any of the choices works.
For example, if you choose x=0 and use that in
(x+2)/2= y/5
(0+2)/2 = y/5
2/2 = y/5
or 1= y/5
y must be 5 if x is 0. See if (0,5) only works in one of the choices.
