x = 4 and y = 0
4y+4 = 2y+12 4y-2y = 12-4 2y = 8 y = 4
That depends what the value of y is.
4y + 19 = 74y = 7-194y = -124y/4 = -12/4y = -3
4
There are 4.
x = 4 and y = 0
4y+4 = 2y+12 4y-2y = 12-4 2y = 8 y = 4
That depends what the value of y is.
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.
