Question

2x + 5y = 1,
2x + 3y = 3.

By Cross Multiplication Method.

​

Answer 1

Step-by-step explanation:

2x+5y=1---(i)

or, 2x=1-5y

or,x=1-5y/2

again,2x=3-3y---(ii)

or,x=3-3y/2

ATP:

1-5y/2=3-3y/2

or,1-5y=3-3y

or, -5y+3y= 3-1

or, -2y=2

or, y=1

therefore, from (i) we get,

2x+5.1=1

or,2x=1-5

or,x= - 4/2

or, x = -2

ans= x=-2 and y= 1
