A-1

Step-by-step explanation:

18-4x=7x+7

18=11x+7

11=11x

x=1

A

Step-by-step explanation:

Hey There!

This is a parallelogram so opposite sides are congruent including interior ones

So 7x+7=18-4x

Now we just have to solve for x

step 1 subtract 7 from each side

18-7=11

7-7 cancels out

now we have

7x=11-4x

step 2 add 4x to each side

4x+-4x cancels out

7x+4x=11x

now we have

11x=11

step 3 divide each side by 11

11/11 cancels out

11/11=1

x=1

Hope this helps :)
