Answer:
Step-by-step explanation:
Set up a proportion
BE/BC = BD/BA
BE = 3
BC = 2 + 3 = 5
BD = x + 2
BA = x + x + 2
BA = 2x + 2
3/5 = (x + 2) / (2x + 2) Cross multiply
3(2x + 2) = 5 (x + 2) Remove the brackets
6x + 6 = 5x + 10 Subtract 6 from both sides
6x = 5x + 4 Subtract 5x from both sides
x = 4
