Answer:
0.5(−y−2)+y=1
(0.5)(−y)+(0.5)(−2)+y=1
−0.5y+−1+y=1
(−0.5y+y)+(−1)=1
0.5y+−1=1
0.5y−1=1
0.5y−1+1=1+1
0.5y=2
0.5y /0.5 = 2/0.5
y=4
Step-by-step explanation:
I hope this is help you
[tex]0.5( - y - 2) + y = 1 \\ - 0.5y - 1 + y = 1 \\ - 0.5y + y = 1 + 1 \\ 0.5y = 2 \\ y = \frac{2}{0.5} \\ y = 4[/tex]
