Answer:
21
Step-by-step explanation:
The first step is to solve for x. I did this by bringing 4 to one side and combining like terms.
x^2=29-4
x^2=25
x=sqrt25
x=5
Then I plugged x into the second equation.
5^2-4=
25-4=21
Obviously there are easier ways to go about this problem, but this is the way I feel comfortable with.
Hope this helps!
