Question

x+x+x =24
y+y+x=26
z+y+x=21
2z+xy*(y-z)=?

Answer 1

Step-by-step explanation:

x=8

y=9

z=4

then, 2*4+8*9(9-4)

8+405

413.okay.

Answer 2

3x=24

x=24/3

x=8(Ist equation)

2y+8=26

2y=26-8

2y=18

y=18/2

y=9(2nd equation)

z+8+9=21

z+17=21

z=21-17

z=4(3rd equation)

2×4+8×9×(9-4)

=8+72×5

=8+360

=368 is the answer
