Hello there!

79 − 42 = ? − 50


Step 1: Simplify both sides of the equation.


79 − 42 = ? − 50

79 +− 42= ? +− 50

(79 +−42) =? − 50 (Combine Like Terms)

37= ? − 50

Step 2: Flip the equation.


? − 50 = 37

Step 3: Add 50 to both sides.


? −50 + 50 = 37 + 50

?=87


I hope I helped!

Let me know if you need anything else!
