Answer:
![\boxed{x = 7~~and~~y = -3}](https://tex.z-dn.net/?f=%5Cboxed%7Bx%20%3D%207~~and~~y%20%3D%20-3%7D)
.
Step-by-step explanation:
5x + 3y = 26 (times 6) 30x + 18y = 156
6x + 7y = 21 (times 5) 30x + 35y = 105
.
30x + 18y = 156
<u>30x + 35y = 105 </u> <u> </u>
-17y = 51
![y = \frac{51}{-17}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B51%7D%7B-17%7D)
y = -3
.
Substitute the value of y to one of equations
6x + 7y = 21
6x + 7(-3) = 21
6x - 21 = 21
6x = 21 + 21
6x = 42
![x = \frac{42}{6}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B42%7D%7B6%7D)
x = 7
Answer:
The width should be more than 5 m. So it can be 6,7 ...
Step-by-step explanation:
The length of a flower garden is = 9 m
The width of a flower garden is = w
The area of a flower garden > 45 sq. m
The area of a flower garden = l * b
l * b > 45
9 * b > 45
the width should be more than 5 m. So it can be 6,7 ...
