(2x - 1)(5x + 8)
14 + 2x + 9x - 6 - 11x 14 - 6 + 2x + 9x - 11x The x values cancel themselves out, leaving just the number value The answer is therefore 8.
3x + y + 1 = 0y = - 3x - 12x - 3y + 8 = 03y - 2x - 8 = 03y = 2x + 8y = 2x/3 + 8/3-3x - 1 = 2x/3 + 8/3-9x - 3 = 2x + 8-11x = 11x = -1y = -3x - 1 = 3 - 1 = 2The graphs intersect at the point (-1, 2).
11x - 8 = 8 + 1 Simplify the right hand side: 11x - 8 = 9 Add 8 to both sides: 11x = 17 Divide both sides by 11: x = 17/11 or 16/11
-3x + 6 + 15x =11x + 8 ie -3x + 15x - 11x = 8 - 6 ie x = 2
We will see. 9X - 8 = 69 - 2X add 2X to each side 2X + 9X - 8 = 69 - 2X + 2X 11X - 8 = 69 add 8 to each side 11X - 8 + 8 = 69 + 8 11X = 77 divide both sides by 11 X = 7 Now, check in original equation 9(7) - 8 = 69 - 2(7) 63 - 8 = 69 - 14 55 = 55 so, it checks and 7 is a solution here
2x + 1 = 9 2x = 9 - 1 2x = 8 2x/2 = 8/2 x=4
-11x-1 = -10x-8 -11x+10 = -8+1 -1x = -7 x = 7
11x + 8 = 8x + 20 3x + 8 = 20 3x = 12 x = 4
6x - 9 + 2x + 1 = 8x -8
If you mean 8+11x = -14 then the value of x works out as -2
It is: x^2 +11x +24 = (x+8)(x+3) when factored
