[0.2k+0.3y=1.3],[-1.0+0.5y=2.3]

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

Solve the following equations : 0.2x+0.3y=1.3 0.4x+0.5y=2.3

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

Solve 0*2x+0*3y=1*3;0*4x+0*5y=2*3

The lines (x-2)/1=(y-3)/2=(z-4)/(-k)a n d=(x-1)/k=(y-4)/2=(z-5)/1 are coplanar if a. k=1or-1 b. k=0or-3 c. k=3or-3 d. k=0or-1

The lines (x-2)/1=(y-3)/1=(z-4)/(-k)a n d(x-1)/k=(y-4)/2=(z-5)/1 are coplanar if a. k=1or-1 b. k=0or-3 c. k=3or-3 d. k=0or-1

The lines (x-2)/1=(y-3)/1=(z-4)/(-k) and (x-1)/k=(y-4)/2=(z-5)/1 are coplanar if a. k=1or-1 b. k=0or-3 c. k=3or-3 d. k=0or-1

The lines (x-2)/1=(y-3)/1=(z-4)/(-k) and (x-1)/k=(y-4)/2=(z-5)/1 are coplanar if a. k=1or-1 b. k=0or-3 c. k=3or-3 d. k=0or-1

Find k so that the following equations are consistent: 2x-y+3=0, kx-y+1=0, 5x-y-3=0
