3.5g+12.2 is the simplified expression I believe
Answer:
The brother sold 33 subscriptions
The sister sold 19 subscriptions
Step-by-step explanation:
Let's represent the number is subscription as:
For the brother = a
For the sister = b
a + b =52
The sister sold 5 fewer than twice the number of her brother sold .
a= 2b - 5
Hence, substitute 2b - 5 for a I. The above equation.
a + b =52
2b - 5 + b = 52
3b = 52 + 5
3b = 57
b = 57/3
b = 19
a + b = 52
a + 19 = 52
a = 52 - 19
a = 33
Therefore,
the brother sold 33 subscriptions
the sister sold 19 subscriptions
