 Example: 4x-1 = 2x+6, find the x value? Solution: Make the bases equal so that we can equate exponents. Now 4x-1 = (22)x-1 = 22(x-1) = 22x-2. Therefore 22x-2 = 22x+6 As the bases are equal, the exponents must be equal. That is 2x-2 = x+6 2x-x = 6+2 Therefore x = 8. Directions: Solve the following problems. Also write at least ten examples of your own.
 Q 1: 3x+2 = 32x, find the x value?Answer: Q 2: 6x+2 = 36x-2, find the x value?Answer: Q 3: 3x+2 = 9x-2, find the x value?Answer: Q 4: 4x+2 = 64, find the x value?Answer: Question 5: This question is available to subscribers only! Question 6: This question is available to subscribers only!
