Solve the system by equations. how many solutions does it have? 3x + 4y = 12
-6x - 8y = -24

A. infinitely solutions
B. 1 solution
C. 2 solution
D. no solution

2 solutions

Step-by-step explanation:

in most cases, linear equations have two solutions depending on which unlike terms you decided to simplify first

(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
