In the equation 5x + 3 = 4x, you want to find the value of x. To do this, you need to isolate x on one side of the equation. Here's how you can solve it step by step:
1. Start with the equation: 5x + 3 = 4x
2. Subtract 4x from both sides to get x alone on one side. This is done to get rid of the x term on the right side of the equation and leave x on the left side. The equation becomes: 5x - 4x + 3 = 0x + 3
3. Simplify the equation: x + 3 = 3
4. To isolate x, subtract 3 from both sides: x + 3 - 3 = 3 - 3
5. Simplify: x = 0
Therefore, the value of x in the equation 5x + 3 = 4x is x = 0.
