Answer:
x = 3 and 7
There are two true solutions.
Step-by-step explanation:
To solve
, use inverse operations by squaring both sides of the equal sign.

The quadratic expression can be factored into binomials and set equal to 0 by the zero product property to find x.
(x - 3) ( x - 7) = 0
x-3 = 0 so x=3
x-7 = 0 so x=7
Now check each solution into the original equation to be sure it solve the solution and is not extraneous.

The larger number is 30.
Set up your equation.
x + y = 25
The question tells us one number is 5 less than the other.
The equation now becomes
x -5 = 25
Add 5 to each side to isolate x.
x=30
