Answer 1

2x-1=x+3, next, x=4. use a balance equation for these kinds of questions 

Answer 2

Because the diagonals of a rectangle should bisect each other, DE = BE. This means that 2x - 1 = x + 3. Bringing x to the left side of the equation and -1 to the right side of the equation gives 2x - x = 3 + 1. This means that x = 4.
