Question

I need help on this please

Answer 1

Answer:

a= k=15 c= m=48/7

Step-by-step explanation:

for a.

first, collect like terms. calculate.

2k- 10 = 20

move the constant to the right (10)

2k = 20 + 10

2k = 30

divide both sides.

k= 15.

for c.

first calculate.

12= 3m - 2/3m - 4

multiple both sides.

36= 9m - 2m - 12

collect like terms.

36= 7m - 12

move like terms.

-7m= - 12 - 36

calculate.

-7m= - 48

divide both sides.

m=48/7

hope this was helpful!
