Question

What is the first step to solve the equation A. Square both sides of the equation. B. Add 5 to both sides of the equation. Square. 5, and -3. C. D. None, because there is no solution. 2x-5--3?​

Answer 1

Hi :)

I'd start by adding 5 to both sides of the equation. That would make the equation easier.

`\boldsymbol{√(2x)-5=3}}`

`\boldsymbol{√(2x)=2}`

The next step is to get rid of the radical sign.

Which operation will undo the square root? Squaring.

So that's why we square both sides:

`\boldsymbol{2x=4}`

And Now we just divide both sides by 2

`\boldsymbol{x=2}`
