1. 5x – (x + 3) = }(9x + 18) – 5
CH

Step-by-step explanation:

simplify = 1 /3

 (4x - 3) -  ((1/3 • (9x - 18)) -  5)  = 0

3.1     Pull out like factors :

  9x - 18  =   9 • (x - 2)  

 (4x - 3) -  (3 • (x - 2) -  5)  = 0  

 x + 8  = 0  

5.1      Solve  :    x+8 = 0  

Subtract  8  from both sides of the equation :  

                     x = -8 Ans

(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
