Question

in an express 2 y + 5 x is equal 1 then y iequal to 2it is true or false​

Answer 1

Thanks for your question...

Your required answer :

• It is FALSE .

Reason :

• 2y + 5x = 1

By substitution method :

• $2y + 5x = 1 \\ \\ 2y = 1 - 5x \\ \\ y = \frac{1 - 5x}{2}$

Put value of y in equation :

• $2 \times \frac{1 - 5x}{2} + 5x = 1 \\ \\ 2 \times \frac{1 - 5x + 10x}{2} = 1 \\ \\ 1 + 5x = 1 \\ \\ 5x = 0 \\ \\ x = 0$

Put value of x in equation :

• $2y + 5(0) = 1 \\ \\ 2y = 1 \\ \\ y = \frac{1}{2}$

Step-by-step explanation:

Thanks for your question...

Your required answer :

It is FALSE .

Reason :

2y + 5x = 1

By substitution method :

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

2y+5x=1

2y=1−5x

y=

2

1−5x

Put value of y in equation :

\begin{gathered}2 \times \frac{1 - 5x}{2} + 5x = 1 \\ \\ 2 \times \frac{1 - 5x + 10x}{2} = 1 \\ \\ 1 + 5x = 1 \\ \\ 5x = 0 \\ \\ x = 0\end{gathered}

=1

1+5x=1

5x=0

x=0

Put value of x in equation :

\begin{gathered}2y + 5(0) = 1 \\ \\ 2y = 1 \\ \\ y = \frac{1}{2} \end{gathered}

2y+5(0)=1

2y=1

y=
