Answer:
Take 66 and subtract 10 to get 56
Divide 56 by 2 to get 28 - this is the first number.
Add 10 to 28 to get 38 - this is the second number.
Prove by adding 28 + 38 to get 66
Answer:
+7
Step-by-step explanation:
The obvious answer to this would be 10.
The most simple way to do it would be taking out 3 x from each side of the equation and do 20 = 10 + _
Another way would be to actually solve it.
Let us put into the situation that the unknown variable would be y. The equation then would look like this.
3 x 20 = 3 x (10 + y)
Then solve
3 x 20 = 3 x (10 + y)
-------- ---------------
3 3
20 = 10 + y
20 - 10 = y
10 = y
10 would be the answer
multiply all terms in the second equation by 2 to get the coefficient on the y variable to be -6.

1pound is equal to 16 ounces i get this thru conversion table so you will multiply 8.34 pound to 16 so the answer is 133.44 ounces
