Srry If Im wrng but Hope this helped :)
C^2+7 would equal 88. the first equation states that C=9, so you can just plug in 9 for C
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
