Answer:

x = -2

Explanation:

$\textsf {Square both sides:}\\\\(√(3x+12) )^2 = 3x + 12\\\\(√(x+8) )^2 = x + 8$

(The square of the square root of a value is the value itself

$(√(x) )^2 \;is\;x$ )

The original identity then becomes

$3x + 12 = x + 8\\\\3x - x = 8 - 12\\\\2x = -4\\\\x = -4/2\\\\x = -2$
