2 answers:
To solve for a, you must isolate it.
<span>25=a^2+b^2
First subtract b^2 on both sides of the equation.
b^2 + 25 = a^2
Now square root both sides of the equation.

<span>
That will get rid of b^2 and make it b. Also the square root of 25 is 5. Finally it will get rid of a^2 to make a.
b + 5 = a is the answer.</span>
<span>25=a^2+b^2
First subtract b^2 on both sides of the equation.
