Question

25 + 8y = 5
245 – 4y = –15
The solution to the system is

Answer 1

y = -2.5

Step-by-step explanation:

25 + 8y = 5

You do the opposite of adding 25 and subtract 25 from both sides which gives you -20.

And then you do the opposite of multiplying 8 by y by dividing 8 by y and you do that to both sides.

So -20 divided by 8 equals -2.5.

So y = -2.5
