The difference between two numbers is 16. Five times the smaller is the same as 8 less than twice the larger. Find the numbers
x - the larger number
y - the smaller number
The difference between two numbers is 16.
\(x-y=16 \\
x=16+y\)
Five times the smaller is the same as 8 less than twice the larger.
\(5y=2x-8 \\
5y+8=2x \\
\frac{5}{2}y+4=x \\ \\
x=x \\
16+y=\frac{5}{2}y+4 \\
y-\frac{5}{2}y=4-16 \\
\frac{2}{2}y-\frac{5}{2}y=-12 \\
-\frac{3}{2}y=-12 \\
y=-12 \times (-\frac{2}{3}) \\
y=4 \times 2 \\
y=8 \\ \\
x=16+y=16+8=24\)
The numbers are 24 and 8.
\(x,y-\text{the numbers},~x>y\\\\ x-y=16\\ 5y=2x-8\\\\ x=16+y\\ 5y=2x-8\\\\ 5y=2(16+y)-8\\ 5y=32+2y-8\\ 3y=24\\ y=8\\\\ x-8=16\\ x=24\\\\ \boxed{x=24,y=8}\)
