Identify the augmented matrix for the system of equations and the solution using row operations. 3x + 4y = 23
5x − y = 23

Um, no lo sé, lo siento, solo necesito los puntos

Step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

the answer would be c:   ax + b = ax + c
