Answer:

Explanation:

In this scenario, x = unknown number

1/2(x + 11) = 14

First, you have to distribute the factors in the parentheses with 1/2.

1/2x + 5.5 = 14

Next, you have to cancel out the 5.5 from both sides by subtracting it.

1/2x = 14 - 5.5

1/2x = 8.5

Then, you have to cancel out the 1/2 from both sides, which can be done by multiplying both sides by 2.

x = 8.5(2)

x = 17

Answer is 17
