Answer:
4
Step-by-step explanation:
We need to break the problems down into smaller parts.
First, what do we need to find. Audrey's age!. Consider it this box □ where we can write her age in later.
Now we move to the difficult part: "Because Four times Audrey's age plus 7 is Patricia age"; we can change it to four times Audrey's age is 23, because Patricia is 23.
Now Audrey age is □, so four times □ plus 7 is 23.
From this, we can replace words by numbers and operations like +,×,÷,=,...
4×□ +7=23
because the two sides of the = is equal, the two sides would still be equal if we remove the same amount
4×□ +7 -7= 23-7
then
4×□+(7-7)=16
then
4×□+0=16
then
4×□=16
then we find the best number to fit is 4.
That's how we find Audrey's age
