\sqrt{2x}+2=3\times 4
Multiply both sides by 4.
\sqrt{2x}+2=12
Multiply 3 and 4 to get 12.
\sqrt{2x}=12-2
Subtract 2 from both sides.
\sqrt{2x}=10
Subtract 2 from 12 to get 10.
2x=100
Square both sides of the equation.
\frac{2x}{2}=\frac{100}{2}
Divide both sides by 2.
x=\frac{100}{2}
Dividing by 2 undoes the multiplication by 2.
x=50
Divide 100 by 2.
