Solve X:
−61(x+31)=21(31x−91)
To solve the given equation −61(x+31)=21(31x−91), we will follow these steps:
Step 1: Eliminate the fractions.
- Identify the LCM of the denominators: 6 (from −61) and 9 (from −91). The LCM is 18.
- Multiply each term of the equation by 18 to clear the fractions.
Applying this, the equation becomes:
18×−61(x+31)=18×21(31x−91)
Simplify each term:
- For the left side: 18×−61=−3. Thus, −3(x+31).
- For the right side: 18×21=9. Thus, 9(31x−91).
Now the equation is:
−3(x+31)=9(31x−91)
Step 2: Distribute the terms.
The equation becomes:
- Left side: −3x−1 because −3×31=−1.
- Right side: 3x−1 because 9×31=3 and 9×−91=−1.
Now we have:
−3x−1=3x−1
Step 3: Solve for x.
- Add 3x to both sides: −3x+3x−1=3x+3x−1
- This simplifies to: −1=6x−1
- Add 1 to both sides: −1+1=6x−1+1
- This simplifies to: 0=6x
- Finally, divide both sides by 6: x=60=0
Therefore, the solution to the equation is x=0.
