n - 12 = -9
Add 12 to both sides to isolate the variable n.
n = -9 + 12
n = 3
B) n = 3
Answer:
19 points
Step-by-step explanation:
Given that :
Fabio had 7 points less than 2 times as many points as Carlos
Let Fabio's point = f
Carlos point = c
Equation relating the number of points scored by both players.
Points scored by Fabio = 31
f = 2c - 7
Carlos point = c
31 = 2c - 7
31 + 7 = 2c
38 = 2c
c = 38/2
c = 19
Hence, Carlos's points is 19
