44 = 9x +8 36=9x 4=x
9x+8=7x+22 To solve for x, combine like terms. (Subtract 7x from both sides, and subtract 8 from both sides. This will give you: 2x=14 Divide both sides by 2. The answer is x=7.
x=9
2x + 5x - 1 = 9x 7x - 1 = 9x -1 = 9x - 7x -1 = 2x -1/2=x
-2x2 + 9x - 12 = 0Then apply the quadratic formula.
44 = 9x +8 36=9x 4=x
9x+8=7x+22 To solve for x, combine like terms. (Subtract 7x from both sides, and subtract 8 from both sides. This will give you: 2x=14 Divide both sides by 2. The answer is x=7.
x=9
-9x + 4 = -50 -9x = -50 - 4 -9x = -54 -x = -6 x = 6.
2x + 5x - 1 = 9x 7x - 1 = 9x -1 = 9x - 7x -1 = 2x -1/2=x
-2x2 + 9x - 12 = 0Then apply the quadratic formula.
x - 10x = 9x, so 9x + 3 = 0, so 9x = -3 so x = -1/3
x + 8x = 477 9x = 477 x = 53
2x + 3 = 9x Subtract 2x from both sides: 3 = 7x Divide both sides by 7: 3/7 = x
2x+3=9x 3=9x-2x 3=7x x=3/7
9x = 60x = 60/9 = 6 2/3 (or 6.67)
2x + 9x simplified would be 11x
