Solve the given equation.<br><br> w<br> −<br> 19<br> =<br> 47
butalik [34]

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
