Hello, I was working on a math assignment and I got stuck on these two questions:
7. Solve: Sqrt(2x+25) - 2 Sqrt(x+4) = 1
I know the answer is 0 but I don't know how to remove the Square roots without ending up that x somehow equals 20.
8. Solve:
{ x +2y =16
{
{ Sqrt(x-2) = y-3
What is this question asking me to do? what does the long { containing two terms mean? Does it mean that they want me to find out when (Sqrt(x-2) = y-3=x +2y =16)?
