8x2 + 16x + 8 = 0
The Commutative Property of Addition.
16x + 2 - 8 = 16x + 24 implies 16x - 6 = 16x + 24 subtracting 16x from both sides, this implies: -6 = 24 So the equation has no soultions.

16x-8x+12 = 78+22 16x-8x = 78+22-12 8x = 88 x = 11
8x2 + 16x + 8 = 0
Combine like terms, meaning add 12X plus 4X which is 16X and then you add 25Y plus 15Y which equals 40Y so the answer will be 16x+40y. combine like terms means add the ones with the same variable.
The Commutative Property of Addition.
16x/100 = 3564.28 Multiply both sides by 100: 16x = 356428 Divide both sides by 16: x = 22276.75
16x + 2 - 8 = 16x + 24 implies 16x - 6 = 16x + 24 subtracting 16x from both sides, this implies: -6 = 24 So the equation has no soultions.

16x-8x+12 = 78+22 16x-8x = 78+22-12 8x = 88 x = 11
16x - 8x + 12 = 78 + 22 or simplified to (16x-8x=8x)(78+22=100) 8x + 12 = 100 Simplify some more (Subtract 12 from both sides) 8x = 88 Divide both sides by 8, and x = 11
Combining like terms, 16x + 20 = 180 or 16x = 160 so that x = 10
Assuming you wish to make this equation equal zero, for x2 + 16x + 55 = 0, x = -5.
