Question 171425
General form of linear equation is :
Ax+By+C=0

A) {{{2*x^2+2*y^2=18}}}  x and y is squared then it is not a linear equation
B)  x-y=5
  x-y-5=0  it is a linear equation where A=1,B=-1, C=-5
C)2y-3=7
2y-10=0    it is a linear equation where A=0,B=2, C=-10

D)3xy+5=10
3xy-5=0  it is not linear equation
