The equation relates 3 variables.

7x + 2y = 2

If x = 3, and y = 2. What is the value of z?

z = 25

Step-by-step explanation:

7x + 2y = z

x = 3

y = 2

z = ?

First, let's put in the values we do know.

7 (3) + 2 (2) = z

Let's solve this.

7 * 3 = 21

2 * 2 = 4

21 + 4 = z

Now, we must add the two together to find z.

21 + 4 = 25

25 = z

z = 25
