Question

Solve the equation:-3(2^x+1)-2^x+2+5=0​

Answer 1

Step-by-step explanation:

Given 3(2^x + 1) - 2^x+2 + 5 = 0

         3 * 2^x + 3 - 2^2 * 2^x + 5 = 0

         3 * 2^x - 4 * 2^x + 5 + 3 = 0

         - 1 * 2^x + 8 = 0

          - 2^x + 8 = 0

            2^x = 8

           2^x = 2^3

             x = 3.
