Respuesta :
y=5.4
you would add 5 on both sides because u would want to isolate the variable. Then you would divide by 5 because, again, you want to isolate the variable to know the answer. Then you get 27 over 5 which, in decimal form, gets you 5.4!!!:)
5 less than the product of 5 and a number y is 22. (5y - 5 = 22)
Let's try to work backwards with this.
I
f we add 5 to 22, we get 27. (5y - 5 + 5 = 22 + 5)
27 divided by 5 is 5.4. (5y ÷ 5 = 27 ÷ 5)
Therefore,
y=5.4
Now, we can check this by plugging that into the first equation.
5y - 5 = 22
(5 × 5.4) - 5 = 22
27 - 5 = 22
22 = 22
Because both sides are equal, it proves that the answer is
y = 5.4
