It is: 8x^2 +68x +32
8x+5=4x+13 4x=8 x=2 Therefore, your answer is 2.
-8x + 4 = -4x; (-8+4)x = -4; x = 1.
8x + 8 = 4x 4x + 8 = 0 4x = -8 x = -2
4x+32=-4x+16x4x+32=12x-4x -4x32=8x/8 /84=x
X=5/12
Only if 4 dollars plus 4 dollars equals 8 dollars.And if you had another 4x, you'd have a dozen-x.
2(4x + 4) = (4x - 12) 8x + 8 = 4x - 12 8x - 4x + 8 = 4x - 4x - 12 4x + 8 = -12 4x + 8 - 8 = -12 - 8 4x = -20 4x/4 = -20/4 x = -5
x = -8, y = 10
4x+5 = 8x+10But you are saying4x+5 = 8x+4If this were the case, 8x+10 = 8x+4, and so 10=4Thus there is no possible solution for X.====================================Honk! Go to your room.8x + 4 = 4x + 5Subtract 4x from each side:4x + 4 = 5Subtract 4 from each side:4x = 1Divide each side by 4:x =1/4Check:Left side: 8x + 4 = 8/4 + 4 = 2 + 4 = 6Right side: 4x + 5 = 4/4 + 5 = 1 + 5 = 66 = 6 yay!
(2x - 8)(-4x + 4) = -8x2 + 40x - 32
Are you trying to find x? If so, get all x's to one side, 32=8x-8, then get x alone... 40= 8x then divide by 8... 5=x So at x=5, 4x+32=12x-8
x * -8 = -8x
