Step-by-step explanation:

b. 5n+15=25

=> 5n+15=25

=> 5n=25-15

=> 5n=10

=> n=10/5

 Therefore, n=2

c. q/2=7

=> q/2=7

=> q=7*2

=> q=14

d. r+5=15

=> r+5=15

=> r=15-5

=> r=10

Hope it'll help you.

Step-by-step explanation:

b. 5n + 15 = 25

5n = 25-15

( it is -15 because +15 is in left side then they go on right side so that sign change)

(+ = -)

5n = 10

n=10/5

( it is in 10/5 because 5n is in multiple form then they go on right side in division form

(× = ÷)

n=2

c. q/2=7

q=7×2 (÷ = ×)

q= 14

d. r+5=15

r=15-5 (+ = -)

r=10
