-8x - 10 - 20 = -8x - 30
(x + 4)(x +4) or (x + 4)squared
x = -8, y = 10
8x = 32 so x = 4
y=-10x-4
5x - 4 + 3x = 36 Simplify: 8x - 4 = 36 Add 4 to both sides: 8x = 40 Divide both sides by 8: x = 5
- 8x + 8x = 0 so question is meaningless.
-8x - 10 - 20 = -8x - 30
x=4, y=9 (4,9)
7y+ 8x + 4= 20 + 8x- 8x - 8x7y + 4 = 20- 4 - 47y=16/7 /7y= 2.28the /7 means divide by 7 :)
-14x
5
8x+4 = 2x+28 8x-2x = 28-4 6x = 24 x = 4
x=7 and y=4
-8x + 4 = -4x; (-8+4)x = -4; x = 1.
8x + 3 = 35 8x = 32 x = 4
8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4
