How many solutions does the system have?
8x + 2y = 14
82 + 2y = 4

you can solve the equestion by many rules , but in my point of view the easiest rule is subtraction/addition and subtition method .

Ans X=11.5

Y = -39

8x+2y=14 eqn1

82+2y=4 eqn 2

2y= -78 (4-82)

y = - 39

putting value of y in eqn ..1

we get,

8x+ 2×(-39) =14

8x= 14+78

8x=92

x = 92÷8

x=11.5

it's a subtition method..

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
