Question

1. Pad the of the equation 31x47 y = 15 and 47x +31y = 63.


1.
of the equation 3x + 4y + 7 = 0 and 5x - 7y - 2 = 0
mot the equation 2.2-32.95
de care equation 2x + 3y - 18 - 2y = 2
parution 3-5y -4 and 9x = 2y
in 29-23 - 110 and 23x-29 - 98
profequoty=52x-3y = 4​

Answer 1

Given, 2x+3y+4z=0,3x+4y+6z=0,4x+5y+8z−0
