Answer:
Option 1 is correct.
Step-by-step explanation:
Given two linear equations to us are ,
[tex]\qquad 3x + 7y = 10 \\\\ \qquad x + y = 2 [/tex]
And we have to find which system of linear equations have same answer .
On considering option (1) which is ,
[tex]\qquad 3x + 7y = 10 \\\\ \qquad 2x + 2y = 4 [/tex]
On taking the second equation in this ,
[tex]=> 2x + 2y = 4 \\\\=> 2( x + y ) = 4 \\\\=> x+y =\dfrac{4}{2}}\\\\\boxed{\red{\bf => x + y = 2 } }[/tex]
This is same as the second one given in the Question . And the first one is already same .
Hence option (1) is correct .
