We have the following equation:
To solve this, we first need to subtract the 7 on both sides of the equation.
The equation then becomes:
Now we must square both sides of the equation to get rid of the radical/square root symbol.
Now we have a normal one step equation.
Add 5 on both sides to find x.
<u>x=21</u>
To see if this solution is true, we must substitute 21 back into the original equation.
11=11
Therefore, the solution is true.
