Solve the following equation (find the value of x). Check your answer only after you have an answer in your notebook.

x + 210 = 790 , x = ?

x + 18 = 31 , x = ?

131 = x + 46 , x = ?

It’s okay to make mistakes. Just watch the video explanation and try the next problem. 🙂

x + 210 = 790

x +210 -210 = 790 -210 ( Remove 210 from both sides so that “x” is standing alone)

x = 580

x + 18 = 31

x + 18 – 18 = 31 – 18 ( Remove 18 from both sides so that “x” is standing alone)

x = 13

31 = x + 46

131 – 46 = x + 46 – 46 ( Remove 46 from both sides so that “x” is standing alone)

x = 85
