Solving for x

Question: Solve for x: [tex]$x^2 + 7 = 16$[/tex]

Solution:

1. Isolate the x² term. Subtract 7 from both sides of the equation:

[tex]$x^2 = 9$[/tex]

2. Take the square root of both sides to solve for x:

[tex]$x = \pm \sqrt9$[/tex]

[tex]$x = \pm 3$[/tex]

Final answer:

  • The value of x could be either 3 or -3.
