Answer 1

7)

`\tt 2x-14=x-2`

`\tt 2x-x=14-2`

`\boxed{\tt x=12}`

8)

`\tt -6+7x=5x+10`

`\tt 7x-5x=6+10`

`\boxed{\tt x=8}`

9)

`\tt x-2=2x-6`

`\tt 6-2=x`

`\boxed{\tt x=4}`

~

10)

`\tt 2x+10=4x-10`

`\tt 4x-2x=10+10`

`\tt 2x=20`

`\boxed{\tt x=10}`

11)

`\tt 5x+7=4x+15`

`\tt 5x-4x=15-7`

`\boxed{\tt x=8}`

12)

`\tt 12x=11x+2`

`\tt 12x-11x=2`

`\boxed{\tt x=2}`
