Answer:

m=5

Explanation:

c=30m+50

c=20m+100

substitute

20m+100=30m+50

like terms

100-50=30m-20m

50=10m

m=5

Answer:

m = 5

Explanation:

We know that c = c.

Since c is also equal to 30m+50 and 20m+100, 30m+50 = 20m+100 is just saying c = c. Then we solve that equation:

30m+50 = 20m+100

Same to both sides

10m = 50

divide by 10

m = 5

Let me know if you have any questions
