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.

27x-3=105 27x =105+3 27x = 108 27x/27=108/27 x= 4
27x-3=105 27x=105+3 27x=108 x=108/27 x=4ans
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
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)
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.
