Question

please solve this question friends for me
I am fed up of studying maths and maths

CBSE CLASS X YAAR EXAM KAB KHATAM HONGE

Answer 1

Given Equation is 28m - 15n = 41   ------------ (1)

Given Equation is 21m + 13n = 55   ------------- (2)

On solving (1) * 3 & (2) * 4, we  get

84m - 45n = 123  

84m + 52n = 220

----------------------------

            -97n = -97

                 n = 1.


Substitute n = 1 in above equation, we get

84m - 45n = 123

84m - 45(1) = 123

84m - 45 = 123

84m = 123 + 45

84m = 168

m = 168/84

m  = 2.


Therefore the value of m = 2, n = 1.


Hope this helps!
