Question

in this equation Q-12=8 what is the value A.78 B.101 C.102 D.77

Answer 1

Hi There!

The value of Q should be 20, because 12 taken away from 20 is 8, so Q=20

Hope This Helps :)

Answer 2

We already know the values of the '12' and the '8'.
The only value we need to find is the value of the 'Q'.
Here's how:

The equation:                    Q - 12  =   8

Add  12  to each side:      Q          =  20 .

That's all there is to it.
