Question

Tell whether (5,2) is a solution of {x+3y=11}
{2x-y=3}

Answer 1

I got: 5+6=11
10-2=3 so (5,2) is not a solution. Is this correct?

Answer 2

(5,2), So these are points on a line. One of the ways you can get the answer is put in a graphing calculator.

Answer 3

BTW. you are correct. Because the points do not satisfy the equation.

Answer 4

Thank you!
