What is 18 the sum of 2xx and 5?

Answer 1

To find the sum of 2xx and 5, we first need to determine the value of xx. Since 18 is the sum of 2xx and 5, we can set up the equation 2xx + 5 = 18. By subtracting 5 from both sides, we get 2xx = 13. Dividing by 2 on both sides gives us xx = 6.5. Therefore, 18 is the sum of 2(6.5) and 5.

Answer 2

18 = 2xx + 5 is a linear equation in the variable xx.
