Let x be the number.

Sum of five and 8 times a number: 8x + 5

Fifty plus one half of the number: 50 + (1/2)x

$8x+5=50+\frac{1}{2}x\\\\8x+5-5=50+\frac{1}{2}x-5\\\\8x=45+\frac{1}{2}x\\\\8x-\frac{1}{2}x=45\\\\\frac{16x}{2}-\frac{1}{2}x=45\\\\\frac{16x-x}{2}=45\\\\\frac{15x}{2}=45\\\\x=45*\frac{2}{15}\\\\x=3*2\\\\x=6$
