Answer:
a.x=4
b.x=4
c.(b)
Step-by-step explanation:
We are given that

a. First we adding x on both sides we get


Now, subtract 5 on both sides we get


b.
We are subtracting 9 from both sides we get



We can solve equation both approach a and b
But I prefer (b) because in approach (b)
There are only 3 step in which we can get answer but in approach (a) we can get answer in 4 steps .
Hence, I prefer approach (b)
Answer:23
Step-by-step explanation:
3·2(3)+2+3
=3·6+2+3
=23
Lets Brian => b and Ethan => e so
b=5
e=3+2b
will be the equation of finding free throws.
