Fraction equations

Answer: −1

1. Multiply every term by 18:3(x+10)=1(2x+29).
2. Expand: 3x+30=2x+29.
3. Subtract 2x and 30 from both sides: x=−1.
4. Therefore x=−1.

Answer: 9

1. Multiply every term by 12:3(x+1)=1(2x+12).
2. Expand: 3x+3=2x+12.
3. Subtract 2x and 3 from both sides: x=9.
4. Therefore x=9.

Answer: 3

1. Multiply every term by 12:3(x+6)=1(2x+21).
2. Expand: 3x+18=2x+21.
3. Subtract 2x and 18 from both sides: x=3.
4. Therefore x=3.
