Answer:
n=4
JK=12
KL=13
Step-by-step explanation:
Since JL=25 and JL=3n+5n-7
Then
3n+5n-7=25 simplifying we get
8n-7=25 subtracting 7 from both sides
8n=32 dividing both sides by 8
n=4
JK?
JK=3n bt n=4
JK=3*4
JK=12
KL?
KL=5n-7
KL=5*4-7
KL=13
Answer:
x = 5
Step-by-step explanation:

13 = - 7 + 9x - 5x , that is
13 = - 7 + 4x ( add 7 to both sides )
20 = 4x ( divide both sides by 4 )
5 = x
