While solving the pair of linear equations using cross multiplication method what will be the value of Z in the relation.

Solve the system of equation 2x - 3y = 2  and  x + 2y = 8 by the method of elimination.

Solve the following system of equations using cross multiplication method :  3 x + 4 y = 24 ,  20 x - 11 y = 47

Use the method of elimination to solve each other of the pair of simultaneous equations: x + y = 0  and  x - y = 2

Solve the following system of equations using cross multiplication method :  3x + 4y – 17 = 0 and 4x – 3y – 6 = 0

If x + y = 6 and 3x - y = 4 then x - y is equal to:

How many solutions are there for 7x + y + 3 = 0 and 2x + 5y − 11 = 0 ? (Use cross multiplication method)

If    then    is equal to
