Problema Solution
Three times the sum of a number and 4 is 8 less than one-half the number. Write and solve an equation to find the number.
Answer provided by our tutors
let 'n' represent the number and we interpret "three times the sum of a number and 4" to mean that three is multiplying the sum itself
Three times the sum of a number and 4:
3(n+4)
8 less than one-half the number:
(n/2)-8
we set the two statements equal to each other and solve for 'n':
3n+4=(n/2)-8
n=-8
the number is -8
