look. The statement "Twelve times the sum of eight and a number" is translated into equation this way:
12(8+x), where x is a number
12(8+x)=-29

anonymous · Answer

divide both sides by 12:
12(8+x)/12=-29/12
8+x=-29/12
subtract 8 from both sides:
8+x-8=-29/12 - 8
x=$$-29/12-8$$

anonymous · Answer

I did it this way 
12(8+x)=-29
12 times 8
96+12x=-29
-96
12x=-125
divide 12
x=-10.4
