Answer:

to find Y

-4x + 11y = 15

x - 2y = 0

equal= -3x + 9y= 15

since x=2y

-3(2y) + 9y = 15

-6y + 9y =15

3y = 15

y = 15/ 3

y = 5

to find x

using x=2y

since

y=5

,therefore

x= 2(5)

x= 10

earnstyle [38]

Answer:

Step-by-step explanation:

new length=15+x

width=19+x

then area=(15+x)×(19+x)=285+15x+19x+x²=x²+34x+285 ft²

original area=15×19=285 ft²

then 285+98=x²+34x+285

x²+34x-98=0

x²+34x+17²=98+17²

(x+17)²=98+289=387

x+17=√387=3√43

x=3√43-17 ft
