How do you solve #(3n)/5-2/5=7/10#?

Answer 1

Ethan Adkins

#n=11/6#

#(3n)/5=-2/5=7/10#

#(3n)/5=7/10+2/5#

#(3n)/5=(7+4)/10#

#(3n)/5=11/10#

#3n*10=5*11#

#30n=55#

#n=55/30#

#n=11/6#

To solve the equation (3n)/5 - 2/5 = 7/10:

Add 2/5 to both sides of the equation: (3n)/5 = 7/10 + 2/5
Find a common denominator for 7/10 and 2/5, which is 10. So, 7/10 + 2/5 = 7/10 + 4/10 = 11/10.
Now the equation becomes: (3n)/5 = 11/10
Multiply both sides by 5 to isolate n: (3n)/5 * 5 = 11/10 * 5
Simplify: 3n = 11/2
Divide both sides by 3: (3n)/3 = (11/2)/3
Simplify: n = 11/6 or approximately 1.833.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
