Answer:

Step-by-step explanation:
The area of a trapezoid is calculated using the formula:

We substitute the values into the formula to obtain:

We simplify the parenthesis to get:

We simplify further to obtain;

Answer:
x=47, y=68
Step-by-step explanation:
Add the two equations. Then we get
-y=-68
y=68
Substituting the value of y in the first equation,
8x-6(68)=-32
8x-408=-32
8x=376
x=47
Answer:
