3(u+2)-u=2(u-1)+5

To solve for u, we will start by distributing and combining like terms on both sides of the equation:

3(u+2) - u = 2(u-1) + 5
3u + 6 - u = 2u - 2 + 5
2u + 6 = 2u + 3

Next, we will isolate u on one side of the equation:

2u + 6 = 2u + 3
Subtract 2u from both sides:
6 = 3

There is no solution to this equation.
