4y+4 = 2y+12 4y-2y = 12-4 2y = 8 y = 4
4x+2y = 20 2y = -4x+20 y = -2x+10
-2
Add the two equations you get 5y = 60 so y = 12 and x = 2
Both of them are equations!The solution is (x, y) = (2, 1).
4y+4 = 2y+12 4y-2y = 12-4 2y = 8 y = 4
4x+2y = 20 2y = -4x+20 y = -2x+10
-2
Add the two equations you get 5y = 60 so y = 12 and x = 2
Both of them are equations!The solution is (x, y) = (2, 1).
4y = 2y + 40 4y - 2y = 2y -2y +40 2y = 40 y = 20 check 4(20) = 2(20) +40 80 = 80
what is the slope of the line that has the equation 4x+2y=12?
2x+y=-12-4x-2y=30 x=-y/2+30, you plug this into -12-4x-2y=30 and get -12+2y-120-2y=30 which gives 2y-2y=162. This is not possible, so the equation is unsolvable.

Y= 1/4.
4y + 4 = 2y + 12Subtract 2y from each side of the equation:2y + 4 = 12Subtract 4 from each side:2y = 8Divide each side by 2:y = 4
