Answer:
Step-by-step explanation:
We are given that Twice the difference of a number and 2 is equal to three times the sum of the number and 4. And we have to tell the number.
Let the number be x
Its difference from 2 = x-2
Twice the difference =2(x-2)
Sum of number and 4 = x+4
Three times of the sum : 3(x+4)
Hence 2(x+2)=3(x+4)
2x+2×2=3x+3×4
2x+4=3x+12
Subtracting 12 and 2x from both sides.
4-12=3x-2x
-8=x
Hence the number is -8
