Question

solve:15x+17y=21, 17x+15y=11​

Answer 1

Answer:

x= -2 x= 3

Step-by-step explanation:

Do process of elimination in order to find y, then sub y value into 15x+17y=21.

15x+17y=21 (*17)

17x+15y=11  (*15)

=255x+289y=357

255x+225y=165

x is cancelled so 64y=192

                            y=3

Sub y into 15x +17y=21,

15x+17(3)=21

15x=-30

                            x=-2
