Answer:
w=66
Step-by-step explanation:
w-19=47
Hey There!
So what we want to do is get the variable on one side (w) and the constant on the other
so essentially what I am saying is that we have to get rid of the -19 and to do that we have to add 19
but remember whatever we do to one side we have to do to the other
-19+19 cancels out
47+19=66
therefore
w=66
2-3n=n+10
so two less than three is subtracting two minus three. than three times a number; we dont know that number so we put it as a variable. in this case n. so they are multiplying right now. "is" means equals. than the same number, which is n, plus 10. so add ten with n.
