Question

In the following simultaneous equations 5 - 3 = 19 ; m - 6n = - 7 , if m=5 then find the value of n.​

Answer 1

Answer:

Mulitply second equation by 3 and subract first equation from it,

3(3m+2n)-(4m+6n)=3(28)-54

9m+6n-4m-6n=30

5m=30

m=6

Substitute in first equation,

4(6)+6n=54

6n=54-24

6n=30

n=5
