Question 680549: if the sum of 4 times a number and 6 is multiplied by 3 the result is 5 greater than the opposite of the number. find the number
Let n = 'a number'
sum means + and times means multiply
is means =
and opposite mean negative
greater means +
so the algebraic equation that those words make are:
3(4n+6)=-n+5
12n+18=-n+5
12n+18-18=-n+5-18
12n=-n-13
12n+n=n-n-13
13n=-13
13n/13=-13/13
n=-1
Therefore the number is -1.
Hope that helps, Happy Calculating!
