4m+3n=18.3m-2n=5

5m-3n=19,m-6n=-7

4m-2n=2,6m-5n=9 then n=…………

If 5m-n =3m +4n , then find the values of the following expression: (3m+4n)/(3m-4n)

Solve the simultaneous equations using Cramer's rule 4m+6n=54, 3m+2n=28

Solve the following simultaneous equations using Cramer's rule 4m+6n=54,3m+2n=28 .

If m: n = 3:7 , then (6m – 2n) : (5m + 3n) is equal to

If L= {1, 2, 3, 4}, M= {3, 4, 5, 6} and N= {1, 3, 5}, then verify that L - (M cup N)= (L - M) cap (L - N) .

5m -n = 3m+4n then find the value of the expressions: (m^2+n^2)/(m^2-n^2)
