Answer:
13
Step-by-step explanation:
15 - 4 + 7 - 5 = 13
Simply expand the brackets and subtract and add accordingly.
4n + 8 = n - 7
(In which 'n' represents the unknown number)
(4n + 8): "Eight more than the product of four and a number"
(= n - 7): "Is equivalent to seven less than the same number in equation form."
Subtract 8 from both sides:
4n = n - 15
Subtract n from both sides:
3n = -15
Divide both sides by 3:
n = -5
