so plug in 10 for r which would give you 3(10)=10+5s the multiply 3x10 so you should have 30=10+5s you want to get 5s by its self to subtract 10 to both sides so you should get 20=5s them divide 5 to both sides and you get s=4

s=4.

3r=10+5s
Substitute the value of r=10
=3 x 10=10 + 5s
=30=10 + 5s
=30-10=5s
=20 =5s
=20/5 =s
=4.
