Answer:

a=10.1

k=3

Step-by-step explanation:

Lets solve the first equation first.

94=10a-7

Lets add 7 to both sides.

101=10a

Divide both sides by 10 to isolate a

101/10=a

a=10.1

Lets do the second equation.

7k+10=31

Subtract 10 from both sides

7k=21

Divide 7 by both sides to isolate k

k=3
