No need to expand the brackets in the first step
Simply transfer the 6
x+8=18/6
x+8=3
Transfer 8
x=3-8
x=-5

x=-5

Explanation:

Apply the Distributive Property on the left side, which tells us that a(b+-c)=ab+-ac

6(x+8)=18hArr6x+6(8)=18

Simplifying, we have

6x+48=18

We now want to isolate x. Subtract 48 from both sides:

6xcancel(+48-48)=18-48

6x=-30

Divide both sides by 6:

(cancel6x)/cancel6=-30/6

x=-5
