Answer:
[tex]x = - 4 \\ y = 4[/tex]
Step-by-step explanation:
[tex] - 7x - 6y = 4 \: \: \: \: \: \: ...(1) \\ x = - 3y + 8 \: \: \: \: \: \: \: \: ...(2) \\ [/tex]
Put x = -3y + 8 in equation (1)
[tex] - 7( - 3y + 8) - 6y = 4 \\ 21y - 56 - 6y = 4 \\ 15y = 4 + 56 \\ 15y = 60 \\ \\ y = \frac{60}{15} \\ \\ y = 4[/tex]
put y = 4 in equation (2)
[tex]x = - 3(4) + 8 \\ x = - 12 + 8 \\ x = - 4[/tex]
