Answer 1

Answer:

i) 2x - 3y = 12 --1

4x - 5y = 22 --2

> multiply Eq 1 with 2 on both sides

>>4x - 6y =24. --3

> Subract Eq2 from 3

4x - 6y = 24

4x - 5y = 22. (-)

--------------------

0x - 1y = 2

So, Y=2

substitute y=2 in Eq.1

2x - 3(2) = 12

2x - 6 = 12

2x = 12 - 6

x= (12 - 6)/2

Therefore X=3
