How do you write 4x plus 4y equals 40 or how do you solve it? You would write it 4x+4y=40 you would solve it for y by subtracting 4x from both sides 4y=40-4x then divide all of that by 4y=40-4x/4 that's if you were graphing i have no idea what you're asking hope that helps if it's not too late.
6x = 32 - 4y and 4y - 8 = 6x so 32 - 4y = 4y - 8 ie 40 = 8y so y = 5 and x = 2
3x-4x=12 that means -x equals 12 so x equals -12
4y + 19 = 74y = 7-194y = -124y/4 = -12/4y = -3
4y+4 = 2y+12 4y-2y = 12-4 2y = 8 y = 4
