The answer to the problem of 12X plus 13 equals 9 is x equals -1/3.
1 and 3
9X = 12X - 9 subtract 12X from each side -3X = -9 divide each side by -3 ( remember, dividing negative by negative number = positive number ) X = 3 check 9(3) = 12(3) - 9 27 = 27 checks
It is: 122-4*(9*-2) = 216
The answer to -12x minus 17 equals negative 89 is x equals 6.
No solution. Multiply second equation by 3 and get 12x + 6y = 0 but already stated 12x + 6y = 9...

The answer to the problem of 12X plus 13 equals 9 is x equals -1/3.
1 and 3
4x2 - 12x + 9 = 5; whence, 2x - 3 = ±√5, and 2x = 3 ±√5. Therefore, x = ½ (3 ±√5).
9X = 12X - 9 subtract 12X from each side -3X = -9 divide each side by -3 ( remember, dividing negative by negative number = positive number ) X = 3 check 9(3) = 12(3) - 9 27 = 27 checks
It is: 122-4*(9*-2) = 216
3x multiplied by (12x plus 9) is:3x(12x + 9)= (3x * 12x) + (3x * 9)= 36x2 + 27x
The answer to -12x minus 17 equals negative 89 is x equals 6.
(2x + 3)(2x + 3)
2x + 3 = -92x = -12x = -6
x^2 - 12x + 27 You're looking for factors of 27 that will combine to make 12. (x - 3)(x - 9)
