Sagot :
2(w+2)-8w=-14 -- expand the brackets, multiply the term(s) outside the bracket by the term(s) inside the bracket.
2w+4-8w=-14 -- combine like terms
4-6w=-14 -- add 6w to both sides and add 14 to both sides
18=6w
3=w
w=3
2w+4-8w=-14 -- combine like terms
4-6w=-14 -- add 6w to both sides and add 14 to both sides
18=6w
3=w
w=3
