Answer:

x = 0

Step-by-step explanation:

The distributive property of multiplication states that a(b - c) = a(b) - a(c). We can apply that to the given equation.

3(2 - x) = 6

3(2) - 3(x) = 6 (Apply distributive property on LHS)

6 - 3x = 6 (Simplify LHS)

6 - 6 - 3x = 6 - 6 (Subtract 6 from both sides)

-3x = 0 (Simplify both sides)

\frac{-3x}{-3} =\frac{0}{-3} (Divide both sides by -3)

x = 0 (Simplify)

Hope this helps!

Billy has 80 marbles in his collection.

There are 16 ounces in a pound so we can form a equation 20 x 16 = 320
Then, we do 320 divided by 4 which gives us the figure 80. Hope this has helped you.
