6.4n + -10 = 4.4n + 6
Reorder the terms:
-10 + 6.4n = 4.4n + 6
Reorder the terms:
-10 + 6.4n = 6 + 4.4n
Solving
-10 + 6.4n = 6 + 4.4n
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-4.4n' to each side of the equation.
-10 + 6.4n + -4.4n = 6 + 4.4n + -4.4n
Combine like terms: 6.4n + -4.4n = 2n
-10 + 2n = 6 + 4.4n + -4.4n
Combine like terms: 4.4n + -4.4n = 0.0
-10 + 2n = 6 + 0.0
-10 + 2n = 6
Add '10' to each side of the equation.
-10 + 10 + 2n = 6 + 10
Combine like terms: -10 + 10 = 0
0 + 2n = 6 + 10
2n = 6 + 10
Combine like terms: 6 + 10 = 16
2n = 16
Divide each side by '2'.
n = 8
