साबित करें की निम्नलिखित रेखाएं संगामी हैं। उनके प्रतिच्छेद बिंदु निकालें।
`5x-3y=1, 2x+3y=23, 42x+21y=257`

x+y+z=1 x-2y+3z=2 5x-3y+z=3

1 + 5x + 3y = 9 2x 3y = 12 X = (x, y) - 4

Solve 42x^3y^2div7x^2y^2

If 3y + 3 = 7x , then 21y - 49 x =

8x+3y=25 4x+5y=23 then find x:y .

Find the value of x, if 4x+3y=23 and y=5

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

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

Prove that the following lines are concurrent. Also, find the point of concurrence : 5x -3y = 1, 2x+ 3y = 23, 42x + 21y = 257 .
