d 5 1/2

Explanation:

Answer 2

x=5.5

Explanation:

We can solve this equation by using the various properties and PEMDAS.

First, we would want to subtract 18 on both sides, to even out the equation.

The result is -7x=-38.5

Now we can isolate the x by dividing both sides by -7.

-38/-7=5.5

Thus, x=5.5
