Maria Avila · Answer 1

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.

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
