Answer:
w=3
Step-by-step explanation:
you take 2 over to the three and add two because a sign changes when going over an equal sign. you do the same thing for 19-4= 15 now you have 15=5w 15/5 is equal to 3
Answer:
[tex]{ \tt{3w + 4 = 19 - 2w}} \\ \\ { \tt{3w + 2w = 19 - 4}} \\ \\ { \tt{5w = 15}} \\ \\ { \tt{w = \frac{15}{5} }} \\ \\ { \tt{w = 3}}[/tex]
