Asked by June

why is it when 9x+x= 10x are we adding the x? Please help me to understand

Answers

Answered by Ms. Sue
9x = 9 times x

Suppose that x = 4

9 * 4 = 36
36 + 4 = 40

10 * 4 = 40

You can try that with other values for x -- and it will always come out with
9x + x = 10x

or, just think of x as a unit. If you add 9 balls and 1 ball, you get 10 balls. You can think of x as anything at all. If you add nine of them and one more, you have ten of them.
