Answer:
[tex]\begin{gathered} a.\text{ x=-10} \\ \text{ b. -3-5=-8} \\ c.y=-\frac{1}{5}x-1 \\ d.\text{ x=-5y-5} \end{gathered}[/tex]
Step-by-step explanation:
Solve the equations using inverse operations to solve equations. Remember that addition and subtraction are inverse operations, such as multiplication and division.
Therefore,
[tex]\begin{gathered} a. \\ -x-5=5 \\ x=-5-5 \\ x=-10 \end{gathered}[/tex]
b. Substitute x=3 into the given expression.
[tex]-3-5=-8[/tex]
c. Isolate y in the given equation:
[tex]\begin{gathered} -x-5y=5 \\ 5y=-x-5 \\ y=-\frac{1}{5}x-1 \end{gathered}[/tex]
d. Isolate x in the given equation:
[tex]\begin{gathered} -x-5y=5 \\ x=-5y-5 \end{gathered}[/tex]
