Question

Solve the equation for x. (5 points)

Answer 1

Solution:

I think the equation should be:

$\sqrt{x - 6} + 3 = 10$

If so, collect like terms to make x the subject of formula.

$\sqrt{x - 6} = 10 - 3 \\ \sqrt{x - 6} = 7$

Square both sides due to the presence of square root.

$( \sqrt{x - 6} {)}^{2} = (7 {)}^{2}$

→$x - 6 = 49$

Collect like terms.

$x = 49 + 6$

Therefore: $x = 55$

I hope this helps.
