`(m+2)/(n+3)` = `3/5` and `(m+7)/(n+11)` = `2/3` then solve `m=?`

If (m+n)/(m-n)=7/3 then (m^2-n^2)/(m^2+n^2)=

If m = 3 and n = 2 find the value of 2m^3 +3n^2- 5 m^2n

Solve : (7m - 5n) - (- 4n - 11m)

Find (m+n)-:(m-n) , if : (i) m=(2)/(3) "and" n=(3)/(2) (ii) m=(3)/(4) "and" n=(4)/(3) (iii) m=(4)/(5) "and" n=-(3)/(10)

5n-2m-2n When m=3 and n=7

If M : N = 3 : 5 and M : O = 3 : 7, then what is (M + N) : (N + O)?

If (m + n)/(m + 3n) = (2)/(3) , find : (2n^(2))/(3m^(2) + mn) .
