Is (2, 5) a solution to this system of equations? 10x + y = 17 4x + 2y = 18 No, (2, 5) is not a solution.
Yes, (2, 5) is a solution.

here's the solution,

let's solve for the equations : -

=》

and

=》

now, by multiplying first equation by 2

we get ,

=》

=》

now, let's subtract second equation from the first equation ( just multiplied by 2)

=》

=》

=》

=》

then, plugging value of x as 1 in first equation,

=》

=》

=》

the system of linear equations have a unique solution which is (1 , 7) , so

No, (2 , 5) is not a solution
