Answer: The answer is 3
Step-by-step explanation:
Distribute 5( + 3 ) − 7 = 23 , 5 + 15 − 7 = 23
Subtract the numbers 5n + 15 − 7 = 23, 5 + 8 = 23
Subtract 8 from both sides of the equation 5 + 8 = 23, 5 + 8 −8 = 23 −8
Simplify
Subtract the numbers
5 + 8 - 8 = 2 3 - 8, 5n = 23 - 8
5 = 23 - 8, 5 = 15
Divide both sides of the equation by the same term
5 = 15
5/ 5 = 15/5
Cancel terms that are in both the numerator and denominator
5/ 5 = 15/ 5, n = 15/ 5
Divide the numbers
= 15/5, n = 3
