Answer:

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

8t-r=12t , solve for t

WITCHER [35]

8t-r=12t
Add r to both sides
8t=12t+r
Subtract 12t from both sides so that t can only be on one side
-4t=r
Divide both sides by -4
Final Answer: t= r/-4
