14-4x=2y
divide both sides by 2
7-2x=y
subsitute 7-2x for y
7-2x+2x=7
add like terms
7=7
true
therefor these 2 equations are the same and there are an infinite number of equations

answer is C

Hey, so using the formula A squared + B squared = c squared, you should be able to work these out.

For example the second one would be 3 squared + 4 squared = c squared. So 9+16=25, and then we would root 25 which gives you 5!

Hope this helps!
