Is the ordered pair a solution of the linear system3x3y96xy1

Is the ordered pair a solution of the linear system?{3x-3y=9/6x+y+1 Simplify the expression. 44)28 7 4 - 5 8

43. 3x-3y=9

6x +y =1

To check(1,-2) is soution

3(1) -3(-2)=3+6=9 =Right hand side =9

so (1,-2) is soution of 3x-3y=9

6(1) +(-2)=4 is not equal to right hand side value that is 4

so (1,-2) is not solution .

44 .28/7*4-5*8

(28/7)*4-(5*8)

=4*4-40

=-24

Thank you
