Explanations :
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
