Question

solve
5m-3n=19 ; m-6n=-7​. ​

Answer 1

$\sf \pmb{Answer :}$

5m - 3n = 19...(i)

m - 6 n= -7...(ii)

Multiplying Eqñ (i) by 2..we get..

10 m - 6n = 38

..

on solving

10 m -6n = 38

m - 6n = -7

___________

9 m = 45

m = 45/9

m = 5...

m-6n = -7

5 - 6n = -7

-6n = -12

n = 2

Answer 2

Answer:

5m -3n = 19 ---1equation

m-6n =-7 ----2equation

_______________

[ 5m -3n = 19 ] ×1

[ m -6n = -7 ] × 5

____________, __,

5m -3n = 19

5m -30n = -35

- + +

___________

27n = 54

n = 54/27

n = 2

Putting the value of n in 1equation.

5m -3(n) = 19

5m -(3×2) = 19

5m -6=19

5m = 19+6

5m = 25

m = 25/5

m = 5

___________

n =2

m =5
