Answer:
x = 7
Explanation:
the smallest common denominator between 2 3 and 6 is 6. Multiply the original equation by 6
- 6(x/3 + x/6 = 7/2)
- 6(x / 3) = 2x
- 6(x/6) = x
- 6(7/2) = 3*7 = 21
Result
- 2x + x = 21
- 3x = 21
- 3x/3 = 21/3
- x = 7
Check
- 7/3 + 7/6 = 7/2
- 14/6 + 7/6 = ? 7/2
- 21/6 =? 7/2
- 21/6 = 3.5
- 7/2 = 3.5
Answer: x = 7
