Dada a equação x – 4y = –15, determine os pares ordenados obedecendo ao intervalo numérico –3 ≤ x ≤ 3.

x = –3

–3 – 4y = – 15

– 4y = –15 + 3

– 4y = – 12

4y = 12

y = 3

x = – 2

–2 – 4y = – 15

– 4y = –15 + 2

– 4y = – 13

4y = 13

y = 13/4

x = – 1

–1 – 4y = – 15

– 4y = –15 + 1

– 4y = – 14

4y = 14

y = 14/4 = 7/2

x = 0

0 – 4y = – 15

– 4y = – 15

4y = 15

y = 15/4

x = 1

1 – 4y = – 15

– 4y = – 15 – 1

– 4y = – 16

4y = 16

y = 4

x = 2

2 – 4y = – 15

– 4y = – 15 – 2

– 4y = – 17

4y = 17

y = 17/4

x = 3 

3 – 4y = – 15

– 4y = – 15 – 3

– 4y = – 18

4y = 18

y = 18/4 = 9/2

Não sei se é o que vc necessitava. Abraços.
