Question

solve these two equations 12 = 4k - 2m and 27 = 6k +2m and find the value of K and M.

Answer 1

4k-2m=12 -------(1)
6k+2m=27--------(2)
Add equations (1) and (2)
6k+2m=27
+4k-2m =12
------------------
10k = 39
-----------------
k = 39/10
k = 3.9

Put k = 3.9 in equation (1)
4k -2m = 12
4(3.9) - 2m = 12
15.6 - 2m = 12
-2m = 12 - 15.6
-2m = -3.6
m = -3.6/-2
m = 1.8

Solution (k,m) = (3.9 , 1.8)
