Question

(-1)-y is equal to 5 find the value of y ​

Answer 1

Answer:

(-1)-y=5

-y=5+1

-y=6

y= -6 ans.

Answer 2

Step-by-step explanation:

The values of x and y are 2.25 and 0.25 resp.

Step-by-step explanation:

Since we have given that

\begin{gathered}x-y=2\\\\\dfrac{2}{x+y}=\dfrac{1}{5}\\\\x+y=\dfrac{5}{2}=2.5\end{gathered}

x−y=2

x+y

2

=

5

1

x+y=

2

5

=2.5

So, from both the equations, we get that

\begin{gathered}x-y=2\\\\x+y=2.5\\\\-------------------\\\\2x=4.5\\\\x=\dfrac{4.5}{2}\\\\x=2.25\end{gathered}

x−y=2

x+y=2.5

−−−−−−−−−−−−−−−−−−−

2x=4.5

x=

2

4.5

x=2.25

So, the value of y would be

\begin{gathered}x-y=2\\\\2.25-y=2\\\\-y=2-2.25\\\\-y=-0.25\\\\y=0.25\end{gathered}

x−y=2

2.25−y=2

−y=2−2.25

−y=−0.25

y=0.25

Hence, the values of x and y are 2.25 and 0.25 resp.
