You can't solve it. But you can simplify it to get: 4x+y=2
How do you solve 4y plus x equals 8
x = 4 and y = 0
4y + 7 = 19 ∴ 4y = 12 ∴ y = 3
y = 31
4y+2 = 2y+6 4y-2y = 6-2 2y = 4 y = 2
You cannot solve one equation in two unknowns.
For 4y+228 = 352 the value of y works out as 31.
x = 5, y = -1
2y = 4x + 4y = 2x + 2
16X - 2Y = 4- 2Y = - 16X + 4Y = 8X - 2---------------m(slope) = 8===========
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.
You need three independent equations to solve for three unknown variables.
