3x-4y=10 , 4x+3y=5

Solve : (7 + x)/(5) - (2x - y)/(4) = 3y - 5 (5y - 7)/(2) + (4x - 3)/(6) = 18 - 5x

Draw the graph of each of the following : (i)(x)/(3)+(y)/(5)=1 , (ii) (2x+6)/(5)=y-1 , (iii) 3x+4y=12 , (iv)3x-y=2

Solve: {:(3y + 2x = 0),(4y + 3x = 5):}

Factorize each of the following expressions : 54 x^6y+2x^3y^4 , 8x^2y^3-x^5

The lines parallel to the normal to the curve x y=1 is/are 3x+4y+5=0 (b) 3x-4y+5=0 4x+3y+5=0 (d) 3y-4x+5=0

The lines parallel to the normal to the curve x y=1 is/are (a) 3x+4y+5=0 (b) 3x-4y+5=0 (c) 4x+3y+5=0 (d) 3y-4x+5=0
