To solve the equation \( 2x - 1 = 4x + 3 \), we can follow these steps:
-
Subtract \( 2x \) from both sides: \[ -1 = 2x + 3 \]
-
Next, subtract \( 3 \) from both sides: \[ -1 - 3 = 2x \] \[ -4 = 2x \]
-
Now, divide both sides by \( 2 \): \[ x = -2 \]
Thus, the solution to the equation \( 2x - 1 = 4x + 3 \) is \( x = -2 \).
The correct response is: -2
