step 1: distribute.
Multiply 2 time x and 2 times 2 that would give you 2x+4+8=6.
step 2: combine like terms.
Add 4 and 8 and it would give you 2x+12=6.
step 3: substract 12 in both sides.
6-12= -6 it would end up being (2x= -6).
step 4: divide 2 in both sides.
2 divided by -6 gives you -3.
Answer:
x= -3
