Answer:
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 :)
