Question

12=4k-2m and 27 = 6k - 2m solve for value k and m
​

Answer 1

Step-by-step explanation:

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)
