Question 554449
if we let x equal the number, then:
"the quotient of twice a number and 8" becomes: 
2x/8
"the quotient of twice a number and 8 added to 4" becomes: 
2x/8 + 4
"the quotient of twice a number and 8 added to 4 equals 16 becomes:
2x/8 + 4 = 16
solve that equation for your answer.
subtract 4 from both sides of the equation to get:
2x/8 = 12
multiply both sides of that equation by 8 to get:
2x = 96
divide both sides of that equation by 2 to get:
x = 48
that should be your answer.
