The solution to a system of linear equations is ( - 3, - 3). Which system of linear equations has this point as its solution? A. x - 5y = - 12 and 3x + 2y = - 15 B. X - 5y = - 12 and 3x + 2y = 15 C. X - 5y = 12 and 3x + 2y = - 15 D. X - 5y = 12 and 3x + 2y = 15.
En resumen
This problem can be solved in 2 ways, by solving each system or by evaluating the solution in each system. I prefer the second since it is faster, at least for me. After evaluating, the answer is C.

No tiene solución porque la T debería tener el valor de 0 , y T + E no podría dar Y y además los números no pueden empezar por 0 espero que te ayude a mi me tocó hacerlo.

Anabella - 2x + y = 8 (1) - 3x - y = 7 (2) Sumando (1) + ( 2) - 5x = 15 x = 15 / ( - 5) x = - 3 X en (1) [si prefieres, puedes usar (2)] - 2( - 3) + y = 8 6 + y = 8 y = 8 - 6 y = 2 Alternativa A.
