3x=81 3x/3=81/3x=27
If 3x = 81 then x = 27 and 27 cubed = 19683
If 3X-27= 0 then X=9
- If 3X - 1 = 11, what is the value of X^2 + X?
3x - 1 = 27 So 3x = 28 and x = 28/3 = 91/3
3x=81 3x/3=81/3x=27
If 3x = 81 then x = 27 and 27 cubed = 19683
-27
3(5-x) = 27 15 - 3x = 27 15 - 3x + 3x = 27 + 3x 15 = 27 + 3x 15 - 27 = 27 - 27 + 3x -12 = 3x -4 = x To check 3(5- -4) ? 27 15 - -12 ? 27 15 + 12 = 27
If you mean: 2/3x -7 = 11 then the value of x works out as 1/27 Check: 2/(3*1/27 -7) = 11
The value of x is the solution of 4 3x plus 5 17 is given as follows . 12 x + 5 =17. 12x =12. Hence , x=1. ThusThe value of x is the solution of 4 3x plus 5 17 is 1.
4+3x-27=-12 To solve it... 3x= -12-4+27 3x= 11 x= 11/3 x= 3.666
If 3X-27= 0 then X=9
2x + x = -27 3x = -27 3x/3 = -27/3 x = -9
What is x in 3x-9 EQUALS 27? X= 36 THIS IS THE WORK: 27 + 9= 36 36/3= 12 :)
Do you mean "what is the value of x when 3x - 2x = 15?" in that case, the value of x is 15
IF 3X-1=11, WHAT IS THE VALUE OF X 2 + X?
