N-5÷2=5 help ASAP PLEASE!!!!!
Alinara [238K]

Answer:

7.5 or 15/2 (Whatever form you need to use)

Step-by-step explanation:

N-5 divided by 2 =5

Combine like terms:

-5 divided by 2= -2.5.

N-2.5=5

Add -2.5 from itself, then do the same to the other side:

N-2.5=5

 +2.5=+2.5 (Adding 2.5 to -2.5 cancels it out)

N=7.5

4x=8-5\\4x=3

Divide by 4 both sides

x=\frac{3}{4}
