Question

The equation relates 3 variables.

7x + 2y = 2
If x= 3, and y = 2. What is the value of z?

Answer 1

z = 25

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
