So we would solve this like

 

8x + 4 = 28     ( first out here we would take 4 to the other side of the equal sign and also change it from positive to negative)

 

8x = 28 - 4       ( now we would simply subtract 4 and 28)

 

8x = 24    ( and now we will take 8 to the other side and divide it by 24 and so this will give us our x )

 

x = 24 /8          ( and now dividing them both will simply give us our answer)

 

x = 3       ANSWER

 

I hope u have understoodthis by now but if not then pls be free to ask!

 

i hope this helps!
