Answer:

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)

$\tt 12x=11x+2$

$\tt 12x-11x=2$

$\boxed{\tt x=2}$
