Use substitution to prove that 2s + 3s is not

equivalent to 5s.

Answer: so no matter what substitution you put in for the variable s you will always get equivalent for 5s ...

Step-by-step explanation:

when s=1 2 (1) + 3 (1) = 5 (1) = 2+3=5 = equivalent

when s=2 2 (2) + 3 (2) = 5 (2) = 4+6=10 = equivalent

when s=3 2 (3) + 3 (3) = 5 (3) = 6+9=15 = equivalent

when s=4 2 (4) + 3 (4) = 5 (4) = 8+12=20 = equivalent

when s=20 2 (20) + 3 (20) = 5 (20) = 40+60=100 = equivalent
