just plug in the y = 3x + 5 into the 4x - y = 5 and solve
then do the for the other equation.

ok the answer is A

anonymous · Answer

no its not

mikeyymonroe · Answer

when you subsitute the y= you get 4x - 3x + 5 = 5 nd you simplify and you get x + 5 = 5 so x=10 then you plug that into y = 3x + 5 and you get y = 3(10) + 5 and you simplify and get y = 35.
x=10, y=35
