Answer:
Kathy's daughter is 8 years old
Step-by-step explanation:
What we know:
Kathy is 33 years old.
That is 7 years younger than 5 times her daughter's age.
With that, the equation 5x - 7 = 33 can be used to find x.
Step 1:
Move "- 7" to the right side of the equation, and find the opposite of it.
5x = 33 + 7
Step 2:
Add "33" and "+7" to get "40."
5x = 40
Step 3:
Divide both side by "5."
5x/5 = 40/5
x = 8
Thus, Kathy's daughter is 8 years old.
