Best Answer

-8X + 7 = 4X - 5

add -8X to both sides

7 = 12X - 5

add 5 to each side

12 = 12X

divide each side by 12

1 = X

check

-8(1) + 7 = 4(1) - 5

-1 = -1

8x+5=4x+13 4x=8 x=2 Therefore, your answer is 2.

8x-5=23+4x 8x-5-4x=23+4x-4x 4x-5=23 4x-5+5=23+5 4x=28 4x/4=28/4 x=7

4x+7-8x=17-4x+7=17-4x=10x = -5/2

8x+5=4x+17 4x=12 subtract 4x from right and 5 from left x=3 divide both sides by 4

X=5/12

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!

8x plus 4y equals 5 is 8x + 4y = 5.

The lines intersect at (3, 5)

8x^2 + 6x - 5 = 8x^2 + 10x - 4x - 5 = 2x * (4x + 5) - (4x + 5) = (2x -1) * (4x + 5)

Y=5-4x to know how I got this do your home work

y=(8x).5 + (4x).5 = (2+2sqrt(2))x.5 y'=(1 + sqrt(2))/sqrt(x)
