Our equation currently is: 4x - 1 = 2x + 5. To solve for x, get x on one side. Subtract 2x from both sides. 2x - 1 = 5 is now our new equation. 2x is not alone. Add 1 to both sides to get 2x alone. 2x = 6 is now our new equation. Now, we must simplify the equation to solve for x. Divide both sides by 2. x = 3 is your solution. I hope this helps!
