x = 3

Number of girls = 5x = 5*3 = 15

they can both be solutions depends on the equation

what is the equation? ?

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
