To solve the system of equations, we have:
- Equation 1: 2r + 2s = 50
- Equation 2: 2r + s = 17
We can start with Equation 2. Let’s isolate s in terms of r:
2r + s = 17
s = 17 - 2r
Now, we can substitute this expression for s in Equation 1:
2r + 2(17 - 2r) = 50
2r + 34 - 4r = 50
-2r + 34 = 50
-2r = 50 - 34
-2r = 16
r = -8
Now that we have r, we can substitute r = -8 back into our expression for s:
s = 17 - 2(-8)
s = 17 + 16
s = 33
So, the solution to the system of equations is:
- r = -8
- s = 33
In conclusion, the values of r and s that satisfy both equations are r = -8 and s = 33.
