Answer:

14/3

Step-by-step explanation:

(5n)/(7+n) = 2

Multiply both sides by 7 + n:

(7 + n) x (5n)/(7 + n) = (7 + n) x 2

5n = 14 + 2n

3n = 14

Divide both sides by 3:

(3n)/3 = 14/3

n = 14/3

Answer:

-1

Step-by-step explanation:

the equation would be 5x+7=2.

so first you'll subtract from both sides so you'll do 2 from 7, whcih equals -5. then you'll divide 5 from each side. 5x÷5=x. -5÷5=-1. so the answer would be -1
