Question

When solving the equation 3y+11=35 , which operation do you "undo" first?

Answer 1

you can really do whatever as long as you keep the equation balanced but if your teacher is expecting something specific from you then you would undo 11 (take away 11 from both sides)

Explanation:

3y + 11 = 35 original equation

3y = 24 subtract 11 from both sides

y = 8 divide both sides by 3 to get y alone

Answer 2

the addition

Explanation:

3y + 11 = 35

-11 -11
