y=(7-x)/4
How do you solve 4y plus x equals 8
-x + 4y = 8
No. They are parallel.
0
x = 4 and y = 0
How do you solve 4y plus x equals 8
-x + 4y = 8
They are parallel lines.
x=4y+1 x=4y-1 No,they have different solutions.
No.
No. They are parallel.
If x - 4y = 2 and x + 4y = 2 then the only solution is when y = 0 and thus x = 2.
Add the two equations and get 4x = 12 so x = 3 and y = -1
5x-4y+9y+x-9+7 = 5x + x - 4y + 9y - 9 + 7 = 6x + 5y - 2 ■

7(3y-2)-(-4y+9)
No.
