Good evening ,

______

Answer:

A. x=all real numbers.

D. x = \frac{2-np}{2}

___________________

Step-by-step explanation:

25-5x=5(-x+5)

25-5x=-5x+25

25-5x=25-5x

Then this equation is valid for all real number x

Note : If you replace x by any number you will get 0 = 0 and that always true.

I need help with my algebra 2. I also want to know how to solve this.
Lisa [10]

Add 1 to both sides:

\sqrt{x+3} = x+1

In cases like this, we have to remember that a root is always positive, so we can square both sides only assuming that

x+1 \geq 0 \iff x \geq -1

Under this assumption, we square both sides and we have

x+3 = (x+1)^2 \iff x+3 = x^2+2x+1 \iff x^2+x-2 = 0

The solutions to this equation are

x = -2,\ x=1

But since we can only accept solutions greater than -1, we discard x=-2 and accept x=1.

In fact, we have

x=-2 \implies \sqrt{-2+3}-1=0\neq -2

and

x=1 \implies \sqrt{4}-1=1

which is the only solution.
