a.(1,3) {5x+2y=11}
{x − y = 7}

Answer 1

O_O! You just plug in x = 1 and y = 3

Answer 2

same for b just plug it in the equation and see if left = right

Answer 3

just plug in the x and y into both equations and see if you get the same answer?

Answer 4

well same solution

Answer 5

not .... for x = 1 and y = 3
1-3 is -2 and that doesn't equal to 7

Answer 6

5x+2x=11 works...
