Question

Help pleaseeeeeeeee :)

Answer 1

x=-3

Explanation:

x+9 = 3.2=6

x= 6-9=-3

Answer 2

`\Large\leadsto \sf (1)/(2) (x \: + \: 9) \: = \: 3`

`\Large\leadsto\sf(1)/(2) x \: + \: (9)/(2) \: = \: 3`

`\Large\leadsto\sf (2x \: +\: 18)/(4) \: = \: 3`

`\large \leadsto\sf 2x \: + \: 18 \: = \: 3 \: * \: 4`

`\large\leadsto\sf2x + \: 18 \: = \: 12`

`\large\leadsto\sf2x \: = 12 \: - \: 18`

`\large\leadsto \sf 2x \: = \: - 6`

`\Large\leadsto\sf \: x \: = \: \cancel\frac { - 6}{2}`

`\large\leadsto\sf \pmb{ \: x \: = \: - 3}`
