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
