8x = 32 so x = 4

- 8x + 8x = 0 so question is meaningless.

x=4, y=9 (4,9)

-14x

7y+ 8x + 4= 20 + 8x- 8x - 8x7y + 4 = 20- 4 - 47y=16/7 /7y= 2.28the /7 means divide by 7 :)

x=7 and y=4

8x+4 = 2x+28 8x-2x = 28-4 6x = 24 x = 4

-8x + 4 = -4x; (-8+4)x = -4; x = 1.

8x + 3 = 35 8x = 32 x = 4

(1, 4)

8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4

8x+2y=4x=-y/4+0.5y=-4x+2

If you mean as an equation in the form of 8x+4 = 68 then x equals 8

8x-4 = -7+5x 8x-5x = -7+4 3x = -3 x = -1

The value of x is 2

-4

It equals 8x+12

(x + 4)(x +4) or (x + 4)squared

8x+2=6x+10 8x-6x=10-2 2x=8 x=4 Therefore, x=4.

x² + 8x - 48 = (x + 12)(x - 4) x² + 8x + 48 = (4+(√32)i)(4-(√32)i)

x = -8, y = 10

If: -8x+4 = 36 then the value of x works out as -4 Check: -8*(-4)+4 = 36

7.75 or 7 and 3/4

f(x)= (4 - 5y)/8 f(y)= (4 - 8x)/5

8x + 8=40 8x=40-8 8x=32 x=32/8 x=4
