Three times a number is three more than twice the number which equation can be used to find the value of x the unknown number

3x = 2x + 3.

Step-by-step explanation:

In the question it has been given that three times a number is three more than twice the number.

Let the number is x.

Then by the given statement 3x = 2x + 3

So equation formed can be used to find the value of x

3x - 2x = 3

x = 3

Therefore, the number is 3 and equation to be solved for x is 3x = 2x + 3.

(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
