Common mistakes made when solving equationsThough the students enjoy solving equations, however in many cases they tend to make mistakes. These mistakes could be because of carelessness or because the child did not understand the concept properly. It is always a good idea to be aware about the common mistakes which students usually make so that these can be corrected from the early age. Here are some of the common mistakes which students usually make when solving equations.☞ 4(5−d)=8 ⇒ 20−d=8The correct answer is 4(5−d)=8 ⇒ 20−4d=8Ways to teach the children to minimize this error ⇒ 4×5−4×d=8 ⇒ 20−4d=8 ☞ 10m+3=9n ⇒ 10m=9n+3The correct answer is 10m+3=9n ⇒ 10m=9n−3Ways to teach the children to minimize this error ⇒ 10m+3−3=9n−3 (subtracting LHS & RHS with the same number) ⇒ 10m+0=9n−3 ⇒ 10m=9n−3 ☞ 8a−5=7b ⇒ 8a=7b−5The correct answer is 8a−5=7b ⇒ 8a=7b+5Ways to teach the children to minimize this error ⇒ 8a−5+5=7b+5 (adding LHS & RHS with the same number) ⇒ 8a+0=7b+5 ⇒ 8a=7b+5 ☞ ½m+7=n ⇒ m+7=2nThe correct answer is ½m+7=n ⇒ m=2(n−7)Ways to teach the children to minimize this error ½m+7=n ⇒ ½m=n−7 ⇒ m=2(n−7) ☞ 4m−5=n ⇒ m−5=¼nThe correct answer is 4m−5=n ⇒ m=¼(n+5)Ways to teach the children to minimize this error 4m−5=n ⇒ 4m=n+5 ⇒ m=¼(n+5) ☞ 1/m+1/n=1/(m+n)The correct answer is 1/m+1/n=(m+n)/mnWays to teach the children to minimize this error 1/m+1/n = (m+n)/mn The best way to remove the above confusion and to ensure the children have less chance of committing mistakes is to practice the problems related to the above situations.
