Solve: 3x/4 – 7/4 = 5x + 12a)52/17b)22/13c)-52/17d)13/29Correct ...
Step 1: Setting Up the Equation
To solve the equation 3x/4 – 7/4 = 5x + 12, we start by eliminating fractions. Multiply the entire equation by 4 to clear the denominators:
- 4 * (3x/4) - 4 * (7/4) = 4 * (5x) + 4 * (12)
This simplifies to:
- 3x - 7 = 20x + 48
Step 2: Rearranging the Equation
Next, we want to get all the terms involving x on one side and constant terms on the other.
- Add 7 to both sides:
- 3x = 20x + 55
- Now, subtract 20x from both sides:
- 3x - 20x = 55
- This simplifies to:
- -17x = 55
Step 3: Solving for x
To isolate x, divide both sides by -17:
- x = 55 / -17
- This gives us:
- x = -55/17
Step 4: Simplifying the Result
We can simplify -55/17 to its equivalent negative fraction. This can be factored:
- -55 = -52 + (-3), so we rewrite it as:
- x = -52/17
The correct answer is indeed option 'C' because it matches our derived solution.
Final Answer
Thus, the solution to the equation 3x/4 – 7/4 = 5x + 12 is:
- x = -52/17 (Option C)
