Question

write four solutions of each of the following equations:
2×
$2x + y = 7$
$x = 4y$
​

Answer 1

$\large{\underline{\underline{\mathfrak{\red{\sf{Solution:-}}}}}}$...

2x + y=7

Put x =0

⇒2(0) + y=7

⇒0+y=7

⇒$\large{\underline{\underline{\mathfrak{\green{\sf{y=7}}}}}}$...

Put x=1

⇒2(1)+y=7

⇒2+y=7

⇒y=7-2.

⇒$\large{\underline{\underline{\mathfrak{\green{\sf{y=5}}}}}}$...

x=4y

Put y=1

⇒x=4(1)

⇒x=4

Put y=2

⇒x=4(2)

⇒$\large{\underline{\underline{\mathfrak{\green{\sf{x=8}}}}}}$...

Answer 2

Step-by-step explanation:

2x + y=7

Put x =0

⇒2(0) + y=7

⇒0+y=7

⇒$\large{\underline{\underline{\mathfrak{\green{\sf{y=7}}}}}}$

...

Put x=1

⇒2(1)+y=7

⇒2+y=7

⇒y=7-2.

⇒$\large{\underline{\underline{\mathfrak{\green{\sf{y=5}}}}}}$

...

x=4y

Put y=1

⇒x=4(1)

⇒x=4

Put y=2

⇒x=4(2)

⇒$\large{\underline{\underline{\mathfrak{\green{\sf{x=8}}}}}}$
