Answer is 11/8

Step by step

5 less than is a subtraction
10 times a number is 10n
Is means =
2 times that number is 2n
Plus 6 is adding

So our equation is

10n - 5 = 2n + 6

Solve for n

Subtract 2n from both sides

10n - 2n - 5 = 2n - 2n + 6

8n - 5 = 6

Now add 5 to both sides to isolate n

8n -5 +5 = 6 + 5

8n = 11

Divide both sides by 8 to Solve for n

8/8 n = 11/8

n = 11/8

Problem solved!
