Hello,
2) the same method as CaptainBlack has demonstrated:
will become:
3) and 4) are ambiguously written, so I can't help you.
5)
6)
7) .
You have to check this answer by re-substituting the result into the original equation because squaring an equation could change something false into a true equation.
8) and 9) are similar to 7). I leave them for you.
10) Isolate the square-root at the LHS of the equation:

Hello, quebec567!
Captain Black is absolutely right.
. . Unless you use parentheses, we have to guess what you meant.
Here are a few more . . .
#2 is the same as #1Subtract 9 from both sides: .
Cube both sides: .
We have: .
#4 is the same as #3.We have: .
Square both sides: .
#6 is the same as #5.We have: .
Square both sides: .
Therefore: .
Square both sides: .
and we have: .
Square both sides: .
Divide by 3: .
Hello,
1. I presume that there must be a typo because you can't solve an equation with 2 variables.
2. Let's pretend that the equation is:
. Now square both sides of the equation:
Now plug in this solution into the original equation and check it.

Please do us a favour and use brackets. For instance your equation is clearly readable if you had written:
9.) 3√(2x+3) = √(y+10)
