Answer: x= 7/3 or Decimal Form: 2.333333....
First let's simplify 5^2 to make our lives easier 5^2 is 25 so the equation is.
25(x-2)+2x-4=9 *ALWAYS USE DISTRIBUTIVE PROPERTY*
so it becomes. 25x-50+2x-4=9 (25 because 25*x is 25x and 25*2 is 50)
(NOW COMBINE LIKE TERMS which means x goes with x and y goes with y ect)
*25x and 2x are like terms and 50, -4 and 9 are like terms*
so 25x+2x=27x
-50+=4= -54
the equation is now: 27x-54= 9 (now add 54 with the 9 to get 63)
27x=63 (now we just divide 63 by 27 to get 7/3)
