No solution.
Step-by-step explanation:
So we have the system of equations:

We can solve this by substitution. Substitute the first equation into the second. Thus:

Distribute the right:

Subtract 4y from both sides:

Subtract the right:

As you can see, this statement is not true. In other words, the system of equations have no solution (likely because the lines are parallel).
And we're done!
So the equation for a trapezoid is

, with the b variable being the 2 bases, h variable for height, and the a variable for area. Firstly, we will need to plug in the appropriate numbers into the equation, and it'll look like this:

Next, we will need to combine 12 and 14, then divide the sum by 2. Your equation should look like this:

Lastly, just divide each side by 13, and your answer should be
