x = 4 and y = 0
4y+4 = 2y+12 4y-2y = 12-4 2y = 8 y = 4
4y + 19 = 74y = 7-194y = -124y/4 = -12/4y = -3
4
8x plus 4y equals 5 is 8x + 4y = 5.
x = 4 and y = 0
4y+4 = 2y+12 4y-2y = 12-4 2y = 8 y = 4
4y + 10 = 22 4y - 10 - 10 4y=12 4y 4y 4y=3
4y + 7 = 19 ∴ 4y = 12 ∴ y = 3
4y + 19 = 74y = 7-194y = -124y/4 = -12/4y = -3
4
8x plus 4y equals 5 is 8x + 4y = 5.
(4, -2)
(12, 1)
y=4
There are infinite solutions, since you have 2 unknowns and 1 equation. x+4y=12 4y=12-x y=3-0.25x or x=12-4y If you choose an y or an x, the other is defined.
How do you solve 4y plus x equals 8
