Answer:
w = 19
Step-by-step explanation:
to evaluate for the value of x in the expression 20 = w + 1 is very simple and direct, just look for a way to make w stand alone , that is look for a way to express w in terms 20 and 1
solution
20 = w + 1
collect the like terms
20 -1 = w
19 = w
w = 19
therefore the value of w in the expression 20 = w + 1 is evaluted to be 19
