You get 50.
Let the unknown number be represented by 'n'. Then, (n x 7) + 8 = 50 7n = 50 -8 = 42 n = 42/7 = 6.
To add seven tenths to a number, multiply the number by 1.7. For example, 50 plus seven tenths of 50 is equal to 50 x (1 + (7/10)) = 50 x 1.7 = 85.
Not too sure about your question but let the number be x:- If: 7x+8 = 50 then x works out as 6 But if: 7x = 42+8 then x works out as 7 and 1/7

First, multiply the original number by 10. Then multiply the original number by 2. Add the two answers that you got and you have just multiplied by 12. For Example: 7x12=(7x10)+(7x2) 70+14 84
40 + 3 50 - 7 43 x 1
The original number is 14.
