Hey there! I'm happy to help!
First we use the distributive property to undo the parentheses.
2w+7=2w+10-8
We combine like terms.
2w+7=2w+2
We subtract 2w from both sides.
7=2
Since we lost our variables and this equation is not true, there are no solutions to this equation as there is no possible value for w that can make this true.
Have a wonderful day! :D
