What do we add to the third of 12 to obtain 10

6

Step-by-step explanation:

"third of 12" is 1/3 x 12

12 x 1/3 = (12 x 1)/3 = 12/3 = 4

Let the number = "x"

4 + x = 10

Isolate the variable (x). Note the equal sign, what you do to one side, you do to the other. Subtract 4 from both sides.

x + 4 (-4) = 10 (-4)

x = 10 - 4

x = 6
