lets use x The sum of that and 6 is 1/2 x + 6

Ten times that is 10 (1/2 x + 6)

The question says that's 8.
So 10 (1/2 x + 6) = 8

Divide each side by 10 : 1/2 x + 6 = 0.8

Subtract 6 from each side: 1/2 x = - 5.2

Multiply each side by 2 : x = - 10.4

What is ten times the sum of half a number and 6 is 8
