Let bus be x and bike be y X × Y = 24 X - Y = 5 *Solve simultaneous Equations using substitution method* X = 5+Y Y(5+y) = 24 Y²+5Y-24=0 *Factorise* Y²+8Y-3Y-24 =0 Y(Y+8)-3(Y+8)= 0 (Y+8)(Y-3)=0 Y = -8 or 3 , We take positive 3 as Y X-y =5 X-3 = 5 so X is 8 Final part X+Y= 8+3= 11 *Correct answer is B👊* If you love❤️ the quizzes I post can you put a like👍
