Question

How do you solve `8=10 (sqrt x) + 3`?

Answer 1

In an equation like this, you first put the `x`'s to one side and the numbers to the other.

Explanation:

Subtract 3 from both sides:
`->5=10sqrtx`

Then you divide both sides by 10 to isolate the `sqrtx`
`->1/2=sqrtx->sqrtx=1/2`

As a final step, you can square both sides:
`->(sqrtx)^2=(1/2)^2->x=1/4`
