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!
