what is x?
25-3x=36
25-3x=36, put all numbers on one side like this:
3x=36 - 25, notice when I moved 25 from left to right, i changed the sign from + to -,
3x=11, divide both sides by 3 and we have,
x=11/3=3 2/3, which is your answer.
Sorry, young person! I missed the - sign in front of your answer. So it should be:
x= -11/3=-3 2/3 . Now that should be right, because:
25 - 3(-3 2/3)=36
25 + 11=36
