Question

solve for x. 2[sqrt x+2]−3=7

Answer 1

The first step is add 3 to both sides to go from

\[\Large 2\sqrt{x+2} - 3 = 7\]

to

\[\Large 2\sqrt{x+2} - 3+3 = 7+3\]

\[\Large 2\sqrt{x+2} + 0 = 10\]

\[\Large 2\sqrt{x+2} = 10\]

Answer 2

Then what's next?

Answer 3

23

Answer 4

first get rid of single numbers, then square the square root and the other side since you are doing the opposite, then subtract the lonely 2

Answer 5

10-2?

Answer 6

not quite, you divide both sides by 2 (to undo the multiplication of 2)

Answer 7

\[\Large \frac{2\sqrt{x+2}}{2} = \frac{10}{2}\]

\[\Large \sqrt{x+2} = 5\]

Answer 8

wouldd that be the end result?
