7x2 - 9x - 10 factor completely?
(7x + 5)(x - 2)
Simplify 5x2 - 7x - 2x - x2?
Separate and simplify the common terms. 5x^2 - X^2 = 4x^2 -7x - 2x = -9x Now put these terms back together 4x^2 - 9x Or if simplified further, you get: x(4x-9)
2y-9x equals 14 solve for y?
2y - 9x = 14 2y = 14 + 9x y = (14 + 9x) / 2
How do you do 24 equals 7x plus 5x?
The 7x and the 5x are like terms. This means that you can add them up. Think about it, 7 x's plus 5x's equals 12x's. From there, you can divide 12 from both sides of the equation, and you will get that x = 2.
7x - 2y equals -2?
Impossible!
What is the answer to 9x-8 equals 7x-3?
9x-8=7x-3 9x-7x=-3+8 2x=5 x=5/2 x=2.5
What is the answe to -7x-2 equals 24-9x?
- 7X - 2 = 24 - 9X add 9X to both sides 2X - 2 = 24 add 2 to both sides 2X = 26 divide both sides by 2 X = 13 ---------------------check in original equation - 7(13) - 2 = 24 - 9(13) - 91 - 2 = 24 - 117 - 93 = - 93 checks
Solve 2x plus 5x-1 equals 9x?
2x + 5x - 1 = 9x 7x - 1 = 9x -1 = 9x - 7x -1 = 2x -1/2=x
How do you do this problem 7x equals 18 -2x?
7x = 18 - 2x 7x + 2x = 18 9x = 18 x = 2
What are the solutions to 9x2 plus 7x equals 2?
9x2 + 7x = 2 9x2 + 7x - 2 = 0 9x2 + 9x - 2x - 2 = 0 9x(x + 1) - 2(x + 1) = 0 (9x - 2)(x + 1) = 0 x ∈ {-1, 2/9}
What does this mean in algebra 9x-27 equals 7 x-1?
9x-27=7x-1 9x-7x= -1+27 26=2x x=26 / 2 therefore x=13
What is 9x equals 7x plus 8?
x = 4 9x = 7x + 8. Subtract 7x from both sides. This leaves 2x = 8. Then divide both sides by 2 to get x by itself. So, x = 4.
9x plus 8 equals 7x plus 22 x equals?
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.
What is the answer to 6-4x equals 7x-9x-2?
6-4x = 7x-9x-2 6-4x = -2x-2 Add 4x to both sides: 6 = 2x-2 Add 2 to both sides: 8 = 2x Divide both sides by 2: 4 = x
What is the answer to 7x plus 2 equals 24?
x = 22/7
What does x equals when 7x equals -5x plus 24?
7X = -5X + 24 add 5X to each side 12X = 24 divide both sides by 12 X = 2 check 7(2) =-5(2) + 24 14 = 14
What is the answer to the equation 9x equals 2x plus 14?
9x=2x+14 subtract 2x from both sides you have 7x = 14 left. divide each side by 7 x=2
