Answer:
x =147
Step-by-step explanation:
The sum of the angles is = 360 -(2x+1) ( since it will make a full circle)
42+(-124+x) =360-(2x+1)
Combine like terms
x-82 =359-2x
Add 2x to each side
x-82+2x = 359
3x -82 = 359
Add 82 to each side
3x-82+82 = 359+82
3x = 441
Divide by 3
3x/3=441/3
x =441/3 or 147
Hey there! :)
Let's simplify it:
Difference = -
Between 5 and twice a number "x" = 5 and 2x
3 = 3
That equals: 5 - 2x = 3, while x = 1
If x = 1, 2 × 1 = 2
5 - 2 = 3
The answer is: 5 - 2x = 3, while x = 1
Hope this helps :)
