100% will be closer to 95% after rounding-off
I would have to go with C and D on this one.
15 + 8(7)=x?
15 + 8(x)= x?
no i think it will be the first one!
15 + 8(7)= x
hope that helped?!!!

Create a system of equations
x + y = 123
5x + y = 343
I use substitution
y = 123 - x
5x + 123 - x = 343
4x + 123 = 343
4x = 220
x = 55
Plug in
x + y = 123
55 + y = 123
y = 68
Check
5x + y = 343
5(55) + 68 = 343
275 + 68 = 343
343 = 343
