5x+7y=12 Original Problem 5(36-7y)+7y=12 Substitute x for 36-7y 180-35y+7y=12 Distributive Property 180-28y=12 Combine Like Terms -28y=-168 Subtract 180 from both sides y=6 Isolate variable y by dividing -28 from both sides.

If im changing the subject of an equation to make x the subject with x^2=n what do i do to the side n when i take ^2 away. do i square it or take the square root?. Does this apply to any power, ie would it be the same if x^(2/1)=n or x^(3+6)=n
