0.4(n-24)=0.8n

Solution for 0.4(n-24)=0.8n equation:

Simplifying
0.4(n + -24) = 0.8n

Reorder the terms:
0.4(-24 + n) = 0.8n
(-24 * 0.4 + n * 0.4) = 0.8n
(-9.6 + 0.4n) = 0.8n

Solving
-9.6 + 0.4n = 0.8n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-0.8n' to each side of the equation.
-9.6 + 0.4n + -0.8n = 0.8n + -0.8n

Combine like terms: 0.4n + -0.8n = -0.4n
-9.6 + -0.4n = 0.8n + -0.8n

Combine like terms: 0.8n + -0.8n = 0.0
-9.6 + -0.4n = 0.0

Add '9.6' to each side of the equation.
-9.6 + 9.6 + -0.4n = 0.0 + 9.6

Combine like terms: -9.6 + 9.6 = 0.0
0.0 + -0.4n = 0.0 + 9.6
-0.4n = 0.0 + 9.6

Combine like terms: 0.0 + 9.6 = 9.6
-0.4n = 9.6

Divide each side by '-0.4'.
n = -24

Simplifying
n = -24
