Solve the system of equations:
First:4x2y=2
Second:y=4x7
4x2(4x7)=2
4x+8x+14=2
12x+14=2
subtract 14 from both sides
x=1
y=4(1)7
y=47
y=3
(1,3)

5x 3 = 11 + 12x combine like figures add 3 to both sides to remove the 3 5x= 14+ 12x Now I get confused. If I remove the 12x I have to subtract 12x from 5x which gives me an answer of 7x=14 would the correct answer thus be x= 2?
