Answer:
(4,-3)
Step-by-step explanation:
Multiplying the bottom equation by -6, we get -6x+12y=-60.
Adding this to the first equation gives 15y=-45, and thus y=-3.
So, it follows that 6x+3(-3)=15, and thus x=4.
To solve for C, you have to get both of the numbers with a C on the same side. So, subtract the 5c from the right side onto the left side.
Then, divide by 3 on each side.
So, c = 7.
area: 18 units^2
Step-by-step explanation:
the shape is a quadrilateral, with one slanted side, so I separated the shape into a rectangle and triangle, and and calculated their area respectively, then added the products up. please correct me if I'm wrong. hope this helped. :)
