Question

What is the solution of the equation: 2x - √(5) + 4 = x?

a) x = -4
b) x = -√5 + 4
c) x = √5 - 4
d) x = 4 - √5

Answer 1

To find the solution of the equation 2x - √(5) + 4 = x, one must isolate x resulting in x = √(5) - 4. Thus, the answer to the equation is choice (c) x = √(5) - 4.

Step-by-step explanation:

The student asked about the solution to the equation 2x - √(5) + 4 = x. To solve this equation, we first want to isolate the variable x on one side. We can do this by subtracting x from both sides of the equation, which gives us:

2x - x = √(5) - 4

Now, we combine like terms on the left side:

x = √(5) - 4

This simplifies to choice (c) x = √(5) - 4, which is the solution to the equation.
