Solve for X:
To solve the equation , we will first distribute the fractions:
With distributed terms, the equation becomes:
.
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:
Now, we'll solve the equation:
1. Add to both sides to gather terms on one side:
2. Add to both sides:
3. Divide both sides by to isolate :
Thus, the solution to the equation is .
Solve for x:
\( 2(4-x)=8 \)
Multiplying by the LCD (16) clears all fractions in one step! This prevents errors and keeps the equation simpler than clearing fractions one by one.
List multiples: 8 (8,16,24...), 4 (4,8,12,16...), 16 (16,32...). The smallest common multiple is 16, so that's your LCD.
Be extra careful with negatives! When you have , remember the negative stays with the x:
Yes, but it's much harder! You'd have to work with fractions throughout. Clearing fractions first makes the algebra much simpler and reduces calculation errors.
Substitute into the original equation: . Both sides equal , so it's correct!
