Best ResponseYou've already chosen the best response.2This is equivalent to the following series of equations: \[x + y = 25\] \[x = y  7\] So, substitute the second equation into the first: \[(y  7) + y = 25\] Simplify, and you'll have y. Then, plug that value of y into the second equation to get x.

Best ResponseYou've already chosen the best response.2This equation gives the perimeter of a rectangle: \[2 \times length + 2 \times width\] In this case, the following is true as well: \[length = 2 \times width + 5\] Substitute this into the first equation and solve like the previous problem.

Best ResponseYou've already chosen the best response.2Then multiply the length times the width to get the area, since: \[Area = length \times width\] Gives the area of a rectangle.
