Answer:
2 5/6 OR 3
Explanation:
1. Divide Both sides by four.
2. -15/-4 can be simplified to 15/4 by removing the negative sign from both the numerator and the denominator.
3. Add 1/2 to both sides
4. Least common multiple of 4 and 2 is 4. Convert 15/4 and 1/2 to fractions with the denominator 4.
5. Since 15/4 and 2/4 have the same denominator, add them by adding their numerators.
6. Add 15 and 2 to get 17.
7. Multiply each side by 2/3, the reciprocal of 3/2 (cancel out 3/2 and leave only X)
8. multiply 17/4 by 2/3 by multiplying numerator times numerator and denominator times denominator.
9. By doing the multiplications 17x2/4x3 you should get 34/12
10. Reduce the fraction 34/12 to lowest terms by extracting and cancelling out 2.
11. You should get 17/6.
Final Step: if you are asked for a mixed number, the answer is 2 5/6 OR if asked for a decimal, put 2.833333333 or 3 IF asked to round.
