Question

PLANO CARTESIANO
A- { 5 x - y = 1
{ 2 x - 3 y = 10

B- { x + 2 y = 12
{ 3 x - y = 22

ME AJUDEM POR FAVOR NÃO CONSIGO RESPONDER.

Answer 1

A) 5×1-4 = 1 ( x= 1 y= 4 )
5×2-9 = 1 ( x=2 y=9 )

2×10-10 = 10 ( x= 10 y= 10 )
2×11-12 = 10 ( x=11 y=12)



B) 2×3+6 = 12 ( x=3 y=6 )
2×4+4 = 12 ( x=4 y=4 )


3×8-2=22 (x=8 y=2)
3×9-5=22 (x=9 y=5 )
