Solve for X:
81(21−x)=41(x−41)
To solve the equation 81(21−x)=41(x−41), we will first distribute the fractions:
- Distribute 81 through (21−x):
- 81⋅21−81x=161−81x
- Distribute 41 through (x−41):
- 41x−41⋅41=41x−161
With distributed terms, the equation becomes:
161−81x=41x−161.
We will eliminate the fractions by multiplying the entire equation by 16, the least common multiple of the denominators 8 and 4, to eliminate fractions:
- 16×(161−81x)=16×(41x−161)
- This simplifies to: 1−2x=4x−1.
Now, we'll solve the equation:
1. Add 2x to both sides to gather x terms on one side:
1=6x−1
2. Add 1 to both sides:
2=6x
3. Divide both sides by 6 to isolate x:
x=62=31
Thus, the solution to the equation is x=31.
