The pair of linear equations 3x + 4y = k, 9x + 12y = 6 has infinitely many solutions if the value of k is
k = 2
k = 6
k ≠ 6
k ≠ 3
The condition for the following system of linear equations to have a unique solution is
ax + by = c

If the units and tens digit of a two digit number are y and x, then the number is
10 y + x
10 x + y
x + y
xy
Solutions of the equations x - y = 3, x + y = 5 are
x = 4, y = 1
x = 4, y = -1
x = 1, y = 4
x = 1, y = -4
The pair of lines5 x - 4 y + 8 = 07 x + 6 y - 9 = 0 represents
parallel lines
coincident lines
intersecting lines
perpendicular lines
The solution of the pair of linear equations 29x + 37y - 103 = 0, 37 x+ 29y - 95 = 0 are
x = 1, y = 2
x = 2, y = 1
x = 2, y = 3
x = 3, y = 2
If the pair of linear equations 5x + ky = -7, x + 2y = 3 is inconsistent, then the value of k is
k = 2/5
k ≠2/5
k = 10
k ≠ 10
