What is the solution to the equation: 2x-5 = -x+7

A: x=4
B: x=12
C: x=2
D: x=-4

D: x=-4

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

answer4 to the second power is 16

and 4 to the third power is 64,
