x =20+6-5-25= - 4. so, x = - 4

Ans 4:

Class : Class 4
Like this :- First we will remove 6 from the left side of the equation and add 6 on the right side this would bring this :- x +25+5=26 Then we will substract 25 from both sides ,this would bring this :- x + 5 = 1 Then we will substract 5 from both sides this will give us :- x = -4 ,so x = -4
