5x - 7y - 5x +6 +3y
Pls step by step. Or just answer!

-4y + 6

Step-by-step explanation:

just remove the opposites collect like terms

(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

you can't solve x because it is 2 linear equation and you only have one equation
