Question

8x+5y-9=0and3+2y=4 solve this using cross multiplication ​

Answer 1

Answer:

1/5 , 1

Step-by-step explanation:

8 + 5y - 9 = 0

5y - 9 = 0 - 8

= 5y - 9 = ( –8)

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

= y = 1/5

3 + 2/y = 4

2/y = 4 - 3 = 1

2/y = 1

= 2 = y × 1 = y

So, y = 1.

In the first case, the value of y is 1/5 while the value of y in the second case is 1.
