[5x+4/2]=12  
open the brackets as there is no need for it at all,,,

5x+4/2=12  

5x+4 =12 * 2

5x + 4 = 24

5x = 24 - 4

5x = 20

x = 20/5

x= 4......

Therefore the value of x is 4 and to verify your answer you can put the value of x in LHS of the equation i.e 5x+4 and you will get answer which is equal to 12 (RHS).</PRE>
