Use substitution to prove that 2s + 3s is not
equivalent to 5s.

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

what?
