3r-5s=-35
2r-5s=-30
multiply equation 2 by -1 then add the two equations. s will cancel and you can solve for r.
Post your work if you need further assistance.
To solve the system of equations:
1. Multiply equation 2 by -1:
-1 * (2r - 5s) = -1 * (-30)
-2r + 5s = 30
2. Add the two equations:
(3r - 5s) + (-2r + 5s) = -35 + 30
3r - 5s - 2r + 5s = -5
3. Simplify terms:
(3r - 2r) + (-5s + 5s) = -5
r + 0 = -5
r = -5
Since s does not appear in the equation anymore, you cannot solve for s using these equations alone. However, if you have additional equations or information, you may be able to find the value of s.
