Solve 7x - 2(x + 1) = 6x + 14

Answer

Step-by-step explanation:

First Simplify  7x-2x-27x−2x−2  to  5x-25x−2.

7x - 2(x + 1) = 6x + 14

second Subtract 5xfrom both sides.

5x−2=6x+14

third  Simplify  6x+14-5 to  x+14

−2=6x+14−5x

fourth Subtract 14 from both sides.

−2=x+14

fifth Simplify  -2-14 to -16

−2−14=x

six  Switch sides.              7 x= -16  

−16=x

x=−16

Step-by-step explanation:

7x−2(x+1)=6x+14

Use the distributive property to multiply −2 by x+1.

7x−2x−2=6x+14

Combine 7x and −2x to get 5x.

5x−2=6x+14

Subtract 6x from both sides.

5x−2−6x=14

Combine 5x and −6x to get −x.

−x−2=14

Add 2 to both sides.

−x=14+2

Add 14 and 2 to get 16.

−x=16

Multiply both sides by −1.

x=−16

(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
