    add 26 to both sides of equation A what do you get?

    add 26 to both sides of the '=' sign in equation y - 26 = 49

    this will simplify to one of the equations in Column |A

    right 0 so we have y = 49 + 26 which is one of the equations in column A

    remember you can do any operation to one side of an equation as long as you do it tio the other side as well . The equation still holds. Its the same equation but in a different form.

    now if you subtract 26 from equation B you'll find its related to one or more equation in column A

    oh hold on equation A is also related to equation 4 take equation 4:- -26 = 49 - y add 26 to both sides 0 = 49 + 26 - y add y to both sides y = 49 + 26

    no its not 23 - you are not looking for a number You are trying to get an equation which is in column A

    EQuation B y + 26 = 49 y + 26 - 26 = 49 - 26 y = 49 - 26

    Its number 3 yes it doesn't matter which side the y is on left or right Its the same equation

    y = 49 - 26 is same as 49 - 26 = y

    now if you manipulate equation 2 you'll find that you can get it equal to B as well
