Solve: (2^x+3) - (2^x) = 56

Question

Can you include steps as well?

Answer 1

(2^x + 3) - (2^x) = 56                 distribute, remove parenthesis

2^x + 3 - 2^x = 56                      combine like terms

3 = 56

 

no solution

 

Have you copied the equation correctly?

Answer 2

2^x+3 - 2^x = 56

 

2^x2³ - 2^x = 56

 

8(2^x) - 2^x = 56

 

7(2^x) = 56

 

2^x = 8

 

2^x = 2³      So, x = 3
