To solve this we simply plug in the value of x where any x's are found in the equation.
1) 27x - 27; x = -9
2) 27(-9) - 27
3) -243 - 27 = -270
So, 27x - 27 = -270 if x = -9.

Solve for x 27x-3 equals 105?
27x-3=105 27x =105+3 27x = 108 27x/27=108/27 x= 4
Solve for x to 27x - 3 equals 105?
27x-3=105 27x=105+3 27x=108 x=108/27 x=4ans
3 equals 27x plus 1?
Is the same as: 27x+1 = 3 Deduct 1 from both sides: 27x+1-1 = 3-1 27x = 2 Divide both sides by 27: x = 2/27
Is the number 1 over 9 a solution to the equation 27x-5 equals 4?
No. The solution to the equation is 1/3. To solve: 27x - 5 = 4 (add 5 to each side to separate knownsa from inkowns) 27x = 9 (now divide both sides by 27 to find the value of x) x = 1/3 (solution)
What is the answer of x when 136-7x equals 20x plus 20?
Add 7x to each side: 136 = 27x + 20 Subtract 20 from each side: 116 = 27x Divide each side by 27: x = 116/27 = 4 & 8/27.
Solve for x 27x-3 equals 105?
27x-3=105 27x =105+3 27x = 108 27x/27=108/27 x= 4
Solve for x to 27x - 3 equals 105?
27x-3=105 27x=105+3 27x=108 x=108/27 x=4ans
What is 27x equals 9?
X = 1/3
3 equals 27x plus 1?
Is the same as: 27x+1 = 3 Deduct 1 from both sides: 27x+1-1 = 3-1 27x = 2 Divide both sides by 27: x = 2/27
How would you factor x3 9x2 27x 27?
x3 + 9x2 + 27x + 27 Given the numbers in the equation, we can likely bet on (x + 3) being a factor. Let's try it with artificial division: 3 * 1 = 3 9 - 3 = 6 3 * 6 = 18 27 - 18 = 9 3 * 9 = 27 27 - 27 = 0 Bingo. So let's carry it out in long division:                       x2 + 6x + 9                    _____________________ x + 3 ) x3 + 9x2 + 27x + 27                        x3 + 3x2                                        6x2 + 27x                                        6x2 + 18x                                                                9x + 27                                                                9x + 27                                                                                    0 So we have: x3 + 9x2 + 27x + 27 = (x + 3)(x2 + 6x + 9) Which we can now factor further with relative ease: = (x + 3)(x + 3)(x + 3) = (x + 3)3
Is the number 1 over 9 a solution to the equation 27x-5 equals 4?
No. The solution to the equation is 1/3. To solve: 27x - 5 = 4 (add 5 to each side to separate knownsa from inkowns) 27x = 9 (now divide both sides by 27 to find the value of x) x = 1/3 (solution)
What is the answer of x when 136-7x equals 20x plus 20?
Add 7x to each side: 136 = 27x + 20 Subtract 20 from each side: 116 = 27x Divide each side by 27: x = 116/27 = 4 & 8/27.
What is 27x squared -90x plus 27 factored to?
27x2 - 90x + 27 = 9*(3x - 1)*(x - 3)
What timeswhat equals 27?
9 times 3 equals 27.
Prime factorization 8 27?
The prime factorization of 8 is 2^3. The prime factorization of 27 is 9 x 3.
What is the intercept of 3x-9y equals -27?
If you want the y-intercept, then you want the value of y when x=0 so3*0 - 9y = -27-9y = -27y = 3If you want the x-intercept, then you want the value of x when y=0 so3x - 9*0 = -273x = -27x = -9
What is x in 3x-9 EQUALS 27?
What is x in 3x-9 EQUALS 27? X= 36 THIS IS THE WORK: 27 + 9= 36 36/3= 12 :)
