Final answer:

The solution to the equation √1-3x = x + 3 is x = -2.


Step-by-step explanation:

The given equation is √1-3x = x + 3. To solve for x, we need to isolate the variable on one side of the equation. Let's begin by subtracting x from both sides:

√1-3x - x = x + 3 - x

√1-4x = 3

To eliminate the square root, we square both sides of the equation:

(√1-4x)^2 = 3^2

1-4x = 9

Next, we solve for x:

-4x = 9 - 1

-4x = 8

x = 8/-4

x = -2

Therefore, x = -2 is the solution to the equation.
