pickupchik [31]
X - the number of people who own a smartphone
y - the number of people who own a flip phone

x:y=4:3
\frac{x}{y}=\frac{4}{3} \\ 4y=3x \\ y=\frac{3}{4}x

500 more people own a smartphone than a flip phone.
x=500+y \\
x=500 + \frac{3}{4}x \\
x-\frac{3}{4}x=500 \\
\frac{1}{4}x=500 \\
x=500 \times 4 \\
x=2000 \\ \\
y=\frac{3}{4}x=\frac{3}{4} \times 2000=3 \times 500 =1500

2000 people own a smartphone and 1500 people own a flip phone.
