[" 2."3x-y=23],[(x)/(3)+(y)/(4)=4]

Solve 3x - y = 23 and (x)/(3) + (y)/(4) = 4.

(x+y)/(2)-(x-y)/(3)=8,(x+y)/(3)+(x-y)/(4)=4

Match the following. {:("Line, parabola"," "," ""Pole"),("I". 2x-3y+4=0,y^(2)=4x," "(a)(4,6)),("II". 2x+3y-4=0,y^(2)=4x," "(b)(2,3)),("III". x-2y+4=0,y^(2)=6x," "(c)(-2,-3)),("IV". 3x+4y-4=0,x^(2)=4y," "(d)(-3//2,-1)):}

If {:[(3,4),(-2,3)]:}{:[(x),(y)]:}={:[(11),(4)]:} , then the values of x, y are given respectively by

If y=x+x^(2)/2+x^(3)/3+x^(4)/4+... then show that x=y-y^(2)/(2!)+y^(3)/(3!)-y^(4)/(4!)+...

[0.2x+0.3y=1.3],[0.4x+0.5y=2.3]
