2\sqrt{a}-3-\left(-3\right)=7-\left(-3\right)
Add 3 to both sides of the equation.
2\sqrt{a}=7-\left(-3\right)
Subtracting -3 from itself leaves 0.
2\sqrt{a}=10
Subtract -3 from 7.
\frac{2\sqrt{a}}{2}=\frac{10}{2}
Divide both sides by 2.
\sqrt{a}=\frac{10}{2}
Dividing by 2 undoes the multiplication by 2.
\sqrt{a}=5
Divide 10 by 2.
a=25
Square both sides of the equation.
