From the image you can get two equations, namely:

y-4 = x+5
3x+5 = x+12

I suggest solving for x in the bottom one and subbing it into eqn 1

baldymcgee6 · Answer

do you get that?

anonymous · Answer

i only got x=7 , if that parts right . im confused on the subbing part

baldymcgee6 · Answer

okay, now that we know x = 7
y-4 = x+5
y - 4 = 7 + 5
y-4 = 12

anonymous · Answer

but why does answer c have multiple y='s ?

anonymous · Answer

would it be A or C ?

baldymcgee6 · Answer

The question states to find the values of the variable as well as the side lengths, these extra values are the side lengths that need to be found.

baldymcgee6 · Answer

So the answer is c
