1. Your system has no solution because you have two parallel lines
To have an infinite number of solutions, the two equations must be one and the same

notice the left side of your second equation is 3 times the left side of your first equation,
so what do you think should happen to the right side ??

How do you solve this by substitution? x=6y+2 3x-18y=4 This is the answer I get: 3(6y+2)-18y=4 18y+6-18y=4 18y+1818y+6-18y+18y=4 36y=10 36 36 Y=5/18 3x-18(5/18) =4 3x-5+5= 4+5 3x= 9 3 3 X=3 (3, 5/18)

Sikve the following by using substitution method x=3y -5 6x-18y = -30 I got this far and I'm stuck 6(3y-5) - 18y = -30 18y - 30 - 18y = -30 -30 = -30 So this doesn't make sense anymore
