Question

What is the value of `x` in the equation `2sqrtx + 20 = 15 + 3sqrtx`?

Answer 1

Combine like terms, then square the root, to end up at `x=25`

Explanation:

We'll combine the `sqrt(x)` terms together, square it, then find our answer.

Let's start with:

`2sqrt(x)+20=15+3sqrt(x)`

We can subtract `2sqrt(x)` and 15 from both sides and end up with:

`sqrt(x)=5`

Then square both sides:

`x=25`
