Feb 9, 2017 · See the entire solution process below: Explanation: Step 1) Because the second equation is already solved for #y#, substitute #5x + 27# for #y# in the first equation and solve …

Jun 11, 2017 · x=6 "change the "color(blue)"base "" from " 9 to 3 rArr(3^2)^x=(3^3)^(x-2) rArr3^(2x)=3^(3x-6) "since the ...

Nov 16, 2015 · You can use the difference of cubes identity to help factor this, but to find all the factors with Real coefficients requires a little more... You can partially factor x^9-27 by first …

Mar 15, 2015 · It is the solution to #27^x=9#. #27^x=9# Because #27=3^3# and #9=3^2#, we must want #(3^3)^x=3^2# But #(3^3)^x=3^(3x)#, so we also want: #3^(3x)=3^2#. Now, it is a …

27^x = 9^(x+2) becomes 27^4 = 9^6 which becomes 531441 = 531441 this confirms the solution is good. ...

Now we solve for x. Adding 3x to each side we get: 5x = -6 Dividing by 5 we get: If we are clever enough to see that 9 is a power of 1/27 (and vice versa) then the solution is a little faster …
