(2x-3y+13)/(7x-3y+22)

2x-3y=13; 7x-2y=20

If the solution of pair of linear equations 2x- 3y= 13 and 7x- 2y= 20 " is " x=2 and y= -3 , then the value of m for which y= mx+7 is _____

Simplify: (3x+2y)(4x+3y)-(2x-y)(7x-3y)

Simplify: (3x+2y)(4x+3y)-\ (2x-y)(7x-3y)

Simplify: (2x+3y)(3x4y)-(7x+3y)(x+2y)

{:(2x - 3y = - 13),(3x - 2y = - 12):}

If x=2 and y=3, then find the values of (i) (2x+3y)/(4x-3y) " "(ii) (2x^(2)-7x+2y)/(2y^(2)-7y+2x)

Simplify: (2x+3y)(3x+4y)-(7x+3y)(x+2y)

{:(2x - 3y = 17),(4x + y = 13):}

{:(2x - 3y = 17),(4x + y = 13):}
