You can put this solution on YOUR website! looks like 1 = w + (1-w)
remove the parentheses to get:
1 = w + 1 - w
this becomes 1 = 1
That is called an identity.
w can be any value and the equation would be true.
the equation being true means that it is not false.
example of a false statement would be:
2 = w + (1 - w)
remove the parentheses and you get:
2 = w + 1 - w
w cancels out again and you are left with:
2 = 1 only this time the statement is false.
-----
a true statement when the unknown variable cancels out means the variable can be any value.
-----
a false statement when the unknown variable cancels out means there is no solution to the problem.
