x+8+x/5 = 20 x = 10
20+2x
20% of 200 is 20/100 * 200 = 40 So 200 increased by 20% is 240.
Suppose the number is N.Then (N + 4)*2 = N + 20that is, 2N + 8 = N + 20subtracting N from both sides gives: N + 8 = 20subtracting 8 from both sides gives: N = 12.
Well, isn't that just a happy little math problem! To find 50% of 20, you simply divide 20 by 2, which gives you 10. Then, you add that 10 back to the original 20, giving you a total of 30. So, 20 increased by 50% is 30.
x+8+x/5 = 20 x = 10
113 + 20 = 133.
20+2x
20% of 200 is 20/100 * 200 = 40 So 200 increased by 20% is 240.

(108 and 1/3)
There will be an overall increase in the first number.
Suppose the number is N.Then (N + 4)*2 = N + 20that is, 2N + 8 = N + 20subtracting N from both sides gives: N + 8 = 20subtracting 8 from both sides gives: N = 12.
