Answer:

Mary is 8 and that Zane and Chase are both 4 years old.

Step-by-step explanation:

For this equation, we will say Mary = M, Zane = Z, and Chase = C.

We will now convert the word problem into equations.

2m = z, 2c - 4 = z, c = 4

Now I will solve the equations by putting C into the equation.

2(4) = 8, 2(4) - 4 = 4, c = 4

So we can see that Mary is 8 and that Zane and Chase are both 4 years old.
