4n+8=3n+5. find the number?

4n - 3n = 5 - 8
n = - 3

4n + 8 = 3n + 5
4n - 3n = -8 + 5
n = 5 - 8
n = -3

n= -3.

4n+8 = 3n+5
4n-3n = 5-8
n = -3

-3.
4n+8=3n+5
-4n_______
8=-1n+5
-5
3=-1n
-3
Answer is -3

subtract n from both sides. then subtract the number from both sides. then get solve for n. N should equal n=-3

-3

4n + 8 = 3n + 5
substract 3n from both sides
4n + 8 - 3n = 3n + 5 - 3n
n + 8 = 5
substract 8 from both sides
n + 8 - 8 = 5 - 8
n = - 3

Subtract both sides by 4n
4n-4n+8=3n-4n+5
Substitute
8=-1n+5
Subtract both sides by 5
8-5=-1n+5-5
Substitute
3=-1n
Divide both sides by -1
3/-1=-1n/-1
Solve
-3=n

You can also see if your right by taking your final answer n=-3 and plugging it in to n in your original equation like this

4(-3)+8=3(-3)+5
-12+8=-9+5
-4=-4

Since both sides are equal the answer n=-3 is correct.

Hope that Helps!

Subtract 3n from both sides.

n + 8 = 5. Subtract 8 from both sides.
n = -3.
