The first step was the combine the like terms; in this example he is subtracting the 3x on both sides of the =.

If you were to solve the equation it would look like this:

2x+6=3x-8
-3x -3x

-x+6=-8
-6 -6

-x=-14
/-1 /-1

x=14

What is the solution to the equation below? √x - 4 = -2 O A. X=& O B. X=4 X = 4 C. x = 6 D. X = 2

Answer:

x = 4

Explanation:

Given the expression;

$\sqrt[]{x}-4\text{ = -2}$

Add 4 to both sides

$\begin{gathered} \sqrt[]{x}-4+4\text{ = -2+4} \\ \sqrt[]{x}=\text{ 2} \end{gathered}$

Square both sides

$\begin{gathered} (\sqrt[]{x})^2=2^2 \\ x\text{ = 4} \end{gathered}$

Hence the value of x is 4
