Question

Ten times the sum of half a number and 6 is 8

Answer 1

" · " - times

" + " - sum

n - a number

0.5n - half a number

10 · (0.5n + 6) = 8     |use distributive property

(10)(0.5n) + (10)(6) = 8

5n + 60 = 8     |substract 60 from both sides

5n = -52    |divide both sides by 5

n = -10.4
