Solve the equation square root of x plus three plus four equals five for the variable. Show each step of your solution process

alekssr [168]

Answer:

$x=-2$

Step-by-step explanation:

The given expression is

$\sqrt{x+3}+4=5$

We group the constant terms on the right hand side to obtain;

$\sqrt{x+3}=5-4$

$\Rightarrow \sqrt{x+3}=1$

We square both sides of the equation to remove the square root.

$\Rightarrow (\sqrt{x+3})^2=1^2$

$x+3=1$

This will simplify to;

$x=1-3$

$x=-2$
