8x + 33 = 7x + 27 Subtract 7x from both sides: x + 33 = 27 Subtract 33 from both sides: x = -6
8x + 6 = 3x - 4 8x = 3x - 4 - 6 8x = 3x - 10 8x - 3x = -10 5x = -10 5x/5 = -10 x = -10/5 x = -2
x2 + 8x + 12 = (x + 6) (x + 2)
8x + 6 = 2x + 24 To solve, collect like terms on each side; collect the x's on the left, the numbers on the right: 8X + 6 = 2x + 24 8x - 2x = 24 - 6 6x = 18 6x / 6 = 18 / 6 x = 3
2(x + 3)(x + 1)
Subtract 8x from each side: -6 = 2x + 6;Subtract 6 from each side: -12 = 2x;Divide each side by 2: x = -6
x=-1First, subtract 6 from both sides of the equation:8x+9=5x+6-6 -68x+3=5x Then subtract 8x from both sides of the equation:-8x -8x3=-3x Then divide both sides by -3/-3 /-3so-1=x
8x + 33 = 7x + 27 Subtract 7x from both sides: x + 33 = 27 Subtract 33 from both sides: x = -6
X= 6 10x + 9 = 8x + 21. subtract 8x and 9 to both sides 2x = 12. divide by 2 to both sides x = 6
16 + 2x = 10 + 8x Subtract 2x from both sides: 16 = 10 + 6x Subtract 10 from both sides: 6 = 6x Divide both sides by 6: 1 = x
8x - 2x - 2 = 3x + 2x + 4 Combine like terms: 6x - 2 = 5x + 4 Subtract 5x from both sides: x - 2 = 4 Add 2 to both sides: x = 6
8x + 7 = 55 Subtract 7 from both sides: 8x = 48 Divide both sides by 8: x = 6
8x + 6 = 3x - 4 8x = 3x - 4 - 6 8x = 3x - 10 8x - 3x = -10 5x = -10 5x/5 = -10 x = -10/5 x = -2
x=1, y=1
x2 + 8x - 6 = 0 x2 + 8x + 16 = 22 (x + 4)2 = 22 x + 4 = ± √22 x = -4 ± √22
j
8x+7=55 8x=55-7 [subtract 7 from both sides] 8x=48 x=48/8 [divide both sides by 8] x=6
