Answer: 6
Step-by-step explanation:
3x -1/2 ×=9+x
(3)x - (1/2)x = 9 + x
(6/2)x - (1/2)x = 9 + x
(5/2)x = 9 + x
(5/2)x - x = 9
(5/2)x - (2/2)x = 9
(3/2) x = 9
3x = 18

Answer:
x = 6
Step-by-step explanation:
3x - 1/2x = 9+x
6x/2 - 1x/2 = 9 + x
5x/2 = 9 + x
5x/2 - 2x/2 = 9
3x/2 = 9
x = 9 × 2/3
x = 18/3
x = 6
Check ⇒ 3x - 1x/2 = 9 + x
x = 6
3 × 6 - 1×6/2 = 9 + 6
18 - 6/2 = 15
18 - 3 = 15
15 = 15
L.H.S = R.H.S
Hence, the answer is correct.
