Solution for the equation 3x + 4 = 2x + 7:
Step 1: Subtract 2x from both sides
3x – 2x + 4 = 7
x + 4 = 7
Step 2: Subtract 4 from both sides
x + 4 – 4 = 7 – 4
x = 3
The solution is x = 3.
Solution for another equation, let’s say 5x – 2 = 3x + 6:
Step 1: Subtract 3x from both sides
5x – 3x – 2 = 6
2x – 2 = 6
Step 2: Add 2 to both sides
2x – 2 + 2 = 6 + 2
2x = 8
Step 3: Divide by 2
2x / 2 = 8 / 2
x = 4
The solution is x = 4.
Solving the Equation ax + b = cx + d for x
In this example, we are given the equation ax + b = cx + d and want to find the value of x.
1. Write down the given equation: ax + b = cx + d.
2. Subtract cx from both sides of the equation to get all terms involving x on one side: ax – cx = d – b.
3. Factor out the x from the left-hand side terms: (a – c)x = d – b.
4. Divide both sides by (a – c) to isolate x: x = (d – b) / (a – c).
Conclusion: The solution to the equation ax + b = cx + d is x = (d – b) / (a – c).
