Dear student, Let the number be xacc to question47×34×x+24=x⇒3x7+24=x⇒3x7-x=-24⇒3x-7x7=-24⇒3x-7x=-24×7⇒-4x=-168⇒4x=168⇒x=1684⇒x=42Thus option (1) is correct Regards

Q 8

Dear student,

L e t t h e n u m b e r b e x a c c . t o q u e s t i o n \frac{4}{7} \times \frac{3}{4} \times x + 24 = x \Rightarrow \frac{3 x}{7} + 24 = x \Rightarrow \frac{3 x}{7} - x = - 24 \Rightarrow \frac{3 x - 7 x}{7} = - 24 \Rightarrow 3 x - 7 x = - 24 \times 7 \Rightarrow - 4 x = - 168 \Rightarrow 4 x = 168 \Rightarrow x = \frac{168}{4} \Rightarrow x = 42 T h u s o p t i o n (1) i s c o r r e c t
