It is: y = -4x+12
4[x+3]=4x+12 4x+12=4x+12 it's open.
4x + 2 + 2x - 2x = 14 4x = 14 - 2 4x = 12 x = 3
if 4x+1=12 4x+1-1=12-1 4x=11 4x/4=11/4 x=11/4
-3y + z = 12
It is: y = -4x+12
what is the slope of the line that has the equation 4x+2y=12?
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
4[x+3]=4x+12 4x+12=4x+12 it's open.
4x + 2 + 2x - 2x = 14 4x = 14 - 2 4x = 12 x = 3
if 4x+1=12 4x+1-1=12-1 4x=11 4x/4=11/4 x=11/4
Without an equality sign it's not an equation but it can be simplified to: 7x-5
(0,6)
-3y + z = 12
-4x + 4y = 1
9x2+9x-12 All I can do is simplify this. I can't solve it unless turn this expression into an equation.
4x - 5 + 1 = 8Add +5 - 1 to both sides of the equation.4x -5 +1 + 5 - 1 = 8 + 5 -14x = 12Divide both sides of the equation by 4.4x/4 = 12/4x = 12/4 = 3
