0.2n-0.15(n+4)=0.25

Solution for 0.2n-0.15(n+4)=0.25 equation:

Simplifying
0.2n + -0.15(n + 4) = 0.25

Reorder the terms:
0.2n + -0.15(4 + n) = 0.25
0.2n + (4 * -0.15 + n * -0.15) = 0.25
0.2n + (-0.6 + -0.15n) = 0.25

Reorder the terms:
-0.6 + 0.2n + -0.15n = 0.25

-0.6 + 0.05n = 0.25

Solving for variable 'n'.

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

Add '0.6' to each side of the equation.
-0.6 + 0.6 + 0.05n = 0.25 + 0.6

Combine like terms: -0.6 + 0.6 = 0.0
0.0 + 0.05n = 0.25 + 0.6
0.05n = 0.25 + 0.6

Combine like terms: 0.25 + 0.6 = 0.85
0.05n = 0.85

Divide each side by '0.05'.
n = 17

Simplifying
n = 17
