Question

Write any 2 solutions for the given linear equation in two variables: x + 2y = 7​

Answer 1

Answer:

Substituting x=1. ,y=5

Step-by-step explanation:

1+5y=7

5y=7-1

5y=6

y=6/5

Answer 2

Given: $x+2y=7$

To find: two solutions for the given equation.

Step-by-step explanation:

$x+2y=7$     $....eqn(1)$

By using hit and trial method,

• Putting  $x=1$ $in$ $eqn(1)$

         $1+2y=7\\2y=7-1\\2y=6\\y=\frac{6}{2}\\ y= 3$

• Putting $x=3$ $in$ $eqn$$(1)$

         $3+2y=7\\2y=7-3\\2y=4\\y=\frac{4}{2}= 2$

        $(1,3)$ $and$ $(3,2)$ are solutions for the given equation.
