0.25+4=0.4(n+4)

Solution for 0.25+4=0.4(n+4) equation:

Simplifying
0.25 + 4 = 0.4(n + 4)

Combine like terms: 0.25 + 4 = 4.25
4.25 = 0.4(n + 4)

Reorder the terms:
4.25 = 0.4(4 + n)
4.25 = (4 * 0.4 + n * 0.4)
4.25 = (1.6 + 0.4n)

Solving
4.25 = 1.6 + 0.4n

Solving for variable 'n'.

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

Add '-0.4n' to each side of the equation.
4.25 + -0.4n = 1.6 + 0.4n + -0.4n

Combine like terms: 0.4n + -0.4n = 0.0
4.25 + -0.4n = 1.6 + 0.0
4.25 + -0.4n = 1.6

Add '-4.25' to each side of the equation.
4.25 + -4.25 + -0.4n = 1.6 + -4.25

Combine like terms: 4.25 + -4.25 = 0.00
0.00 + -0.4n = 1.6 + -4.25
-0.4n = 1.6 + -4.25

Combine like terms: 1.6 + -4.25 = -2.65
-0.4n = -2.65

Divide each side by '-0.4'.
n = 6.625

Simplifying
n = 6.625
