m + s = 26
3m + 8s = 123


Sagot :

Answer:

M=17

S=9

Step-by-step explanation:

m = 17 and s = 9

Refer to the attachment for full solution . The main key here is to multiply first equation by 3 so that in both equations the coefficient of m will be same so that we can eliminate 3m and then we will solve for s and then putting value of s in any of the equation , so we can get m

Note :- You can multiply the 1st equation by 8 too for making coefficient of s same and then solving for m and then solving for s
