Ms. Deangle orders writing journals for each of her students. She has 28 students in her class. After she gives one journal to each of her students, she realizes that she has 7 journals left. She writes the following equation.

w-28=7

you're welcome :)

can you answer another question

w-28=7

state the inverse operation needed to isolate the variable. then, solve the equation

Mar 26th, 2015

add 28 to both sides to get

w -28 +28 = 7+28

w = 35

Mar 26th, 2015

oh okay that makes sense thanks again

Mar 26th, 2015

wait how does w=35

Mar 26th, 2015

35 - 28 = 7

Mar 26th, 2015

oh sorry about that but thanks again :)

Mar 26th, 2015
