sqrt%283x%2B4%29%2B+5+=+9 Start with the given equation


sqrt%283x%2B4%29+=+9-5 Subtract 5 from both sides


sqrt%283x%2B4%29+=+4 Combine like terms.


3x%2B4+=+16 Square both sides. This will eliminate the square root.


3x=16-4 Subtract 4 from both sides.


3x=12 Combine like terms on the right side.


x=%2812%29%2F%283%29 Divide both sides by 3 to isolate x.


x=4 Reduce.
