Question

3.28+y=1.01 z - 3.96 = -2 -4.81-а=3.5

Answer 1

У=1.01-3.28=-2.27
z=-2+3.96=1.96
-a=3.5+4.81
-a=8.31
a=-8.31

Answer 2

It seems like you've provided a system of equations with three equations involving variables y and z, and a:

1. $3.28 + y = 1.01z - 3.96$
2. $-2 - 4.81 - a = 3.5$

However, there's a minor issue with equation 2. It seems like you might have a typo or formatting mistake. Could you please clarify or correct equation 2 so that I can help you solve the system of equations?
