8x+ 5y-9=0,3x + 2y - 4=0​

Answer 1

Answer:

x=-2

y=5

Explaination: In the Photograph

Answer 2

Answer:

8x+5y=9 --------equation(1)

3x+2y=4 --------equation(2)

Step-by-step explanation:

multiplying equation '1' by 2 and equation '2'by 5 and subtracting equation '1' and '2'

16x+10y-(15x+10y)=18-20

16x+10y-15x-10y= -2

x= -2

putting the value of x in equation '2'

3x+2y=4

3*(-2)+2y4

-6+2y=4

2y=4+6

y=10/2

y=5
