(i) Solve
`5x-4y+8`
`7x+6y-9`

On comparing the ratios (a_(1))/(a_(2)), (b_(1))/(b_(2)) and (c_(1))/(c_(2)) , find out whether the lines representing the following pairs of linear equations intersect at a point, are parallel or coincident: 5x-4y+ 8=0 7x+ 6y-9=0

5x - 4y + 8 = 0 7x + 6y - 9= 0

Solve 2x-3y=8:4x-6y=9

Solve fir x and y: [5x-4y+8=0],[7x+6y-9=0]

Solve 3x+2y=4,8x+5y=9

Solve for x and y : 7x - 4y = 49, 5x - 6y=57

6x+4y=5 9x+6y=8

Solve for x and y: 7x - 4y = 49 5x - y = 22

Write all the terms of the algebraic expressions: (i) 4x^(5) - 6y^(4) + 7x^(2) y - 9 (ii) 9x^(3) - 5z^(4) + 7x^(3) y - xyz

The equation of the line passing through the intersection of the lines 3x + 4y = -5, 4x + 6y = 6 and perpendicular to 7x - 5y + 3 = 0 is :
