Solve

5r-8=2
8r+5s=21

5r-8=2

5r = 10
r = 2

8r+5s=21
8(2) + 5s = 21
5s = 21 - 16
s = ?

Would the answer be 5

To solve the system of equations:

1. Solve the first equation, 5r - 8 = 2, for the variable "r".
Add 8 to both sides of the equation:
5r = 10

Divide both sides of the equation by 5:
r = 2

So, the solution for "r" is 2.

2. Substitute the value of "r" (2) into the second equation, 8r + 5s = 21.
Replace "r" with 2:
8(2) + 5s = 21

Simplify:
16 + 5s = 21

Subtract 16 from both sides of the equation:
5s = 5

Divide both sides of the equation by 5:
s = 1

So, the solution for "s" is 1.

Therefore, the solution to the system of equations is r = 2 and s = 1.
