Answer 1

Answer:

x/2+x=9

1/2 x+x=9

3/2 x=9

3x=9*2

x=9*2/3

x=6

Answer 2

$\frac{x}{2} \: + x \: = 9 \\ \\ take \: lcm \: = 2 \\ \\ \frac{x}{2} + \: \frac{x \times 2}{2} \: = 9 \\ \\ \frac{x}{2} \: + \frac{2x}{2} \: = 9 \\ \\ \frac{3x}{2} = 9 \\ \\ x = \frac{9 \times 2}{3} \\ \\ x = 6$

answer x =6
