Answer:
w = 3
Explanation:
4w + 5 = 20 - w
so first you have to know that when there is no number before the variable think of it as one so the w on the right side is 1 w now for the solving,
4w + 5 = 20 - 1w
+ 1 w + 1 w
5w + 5 = 20 and the -w and +w cancel
-5 -5
5w = 15 the +5 and the -5 cancel
5w/5 cancel then divide 15/5 and you get 3 therefore the value of w is 3 hope this helped u sorry if it's incorrect have an amazing day:)
