Answer:
it should equal 23
Step-by-step explanation:
to go from 10y to 5y, divide by 2. this also means you have to divide 46 by 2, which is 23.
[tex]5y=23[/tex] is equivalent to [tex]10y=46[/tex]
you could also solve for y in which [tex]y=4.6[/tex] and plug that into 5y. that will also give you 23
