<h3><u>The first number, x, is equal to 33.</u></h3><h3><u>The second number, y, is equal to 23.</u></h3><h3><u>The third number, z, is equal to 46.</u></h3>

x + y + z = 102

z = 2y

x = 10 + y

Because we have values of x and z, we can plug them into the original equation to solve for y.

10 + y + y + 2y = 102

Combine like terms.

4y + 10 = 102

Subtract 10 from both sides.

4y = 92

Divide both sides by 4.

y = 23

Now that we have a value for y, we can find the value of x and z.

z = 2(23)

z = 46

x = 10 + 23

x = 33
