Solve the following equation

Question

u+2=4

The question for me is how do I solve these types of problem. I already know that u=2, but I need to know the steps to get to the answer.

Thanks,

Answer 1

u+2=4

We need to get the u alone on one side. Subtract 2 from both sides

u+2 - 2 = 4 - 2

u = 4

Answer 2

First thing you want to do is get the letter variable on one side by itself. In order to do this you must subtract two, and whatever you do to one side you must do to the other. u+2=4
u+2-2=4-2;
u=2
