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

Add '-7u' to each side of the equation.
6 + 5u + -7u = 2 + 7u + -7u

Combine like terms: 5u + -7u = -2u
6 + -2u = 2 + 7u + -7u

Combine like terms: 7u + -7u = 0
6 + -2u = 2 + 0
6 + -2u = 2

Add '-6' to each side of the equation.
6 + -6 + -2u = 2 + -6

Combine like terms: 6 + -6 = 0
0 + -2u = 2 + -6
-2u = 2 + -6

Combine like terms: 2 + -6 = -4
-2u = -4

Divide each side by '-2'.
u = 2

Simplifying
u = 2
