Simplifying

5n + -3 = 2n + -8

Reorder the terms:

-3 + 5n = 2n + -8

Reorder the terms:

-3 + 5n = -8 + 2n

Solving

-3 + 5n = -8 + 2n

Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right.

Add '-2n' to each side of the equation. -

3 + 5n + -2n = -8 + 2n + -2n

Combine like terms:

5n + -2n = 3n -3 + 3n = -8 + 2n + -2n

Combine like terms:

2n + -2n = 0 -3 + 3n = -8 + 0 -3 + 3n = -8

Add '3' to each side of the equation. -3 + 3 + 3n = -8 + 3 Combine like terms:

-3 + 3 = 0 0 + 3n = -8 + 3

3n = -8 + 3

Combine like terms:

-8 + 3 = -5 3n = -5

Divide each side by '3'. n = -1.666666667

Simplifying n = -1.666666667
