Answer:

multiply all terms in the top equation by 2
multiply all terms in the second equation by -7. it would then add the two equations together to cancel out the variable x
You will then have two equations in terms of y
solve for y and either equation then substitute that value for y into the other equation then solve for x
Answer:
51ft^2
Step-by-step explanation:
Given data
Side of square patio= 9ft
Area= 9*9= 81 ft^2
New length = 9+3= 12ft
New Widht = 9+2= 11ft
New Area= 12*11
New Area= 132ft^2
Hence the area added is
=132-81
=51ft^2
