22x - 3  = 32

 

The trick here is to equate bases

 

Note that 32  = 25     .....so.....

 

22x - 3  =  25          since the bases are the same we can solve for the exponents

 

2x  - 3   = 5          add 3 to both sides

 

2x  = 8                divide both sides by 2

 

x  = 4 

 

 

 

cool cool cool
