Answer:
w = 23
Step-by-step explanation:
You are solving for the variable, w. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS, & isolate the variable, w.
First add 4 to both sides:
w - 4 = 19
w - 4 (+4) = 19 (+4)
w = 19 + 4
Simplify:
w = 19 + 4
w = 23
w = 23 is your answer.
