As the square root and square has the invers to each other.. After solving the given equation the value of the x obtained is 42 units.
Given information
The given equation is,
[tex]\sqrt{x+2}-15=-3 [/tex]
Add the number 15 both the sides,
[tex]\begin{aligned}\\ \sqrt{x+2}-15+15&=-3 +15\\ \sqrt{x+2}&=12\\ \end[/tex]
Square both sides,
[tex](\sqrt{x+2})^2=12^2[/tex]
As the square root and square has the invers to each other. Thus the square cancel the square root. Thus,
[tex]{x+2}=144[/tex]
Solve further for the x
[tex]x=144-2\\ x=142[/tex]
Hence after solving the given equation the value of the x obtained is 42 units.
