Subject: Solving algebraic equations
Hello to you all, I live in Scotland and I remember my early secondary high school algebra days. When I was 14, way back in the early 60's teachers just wrote algebraic equations up on the blackboard and expected youngsters to 'do it' I was a youngster who couldn't do it.............no clue! Over the years the cloud vanished and I found it so easy. This is what I told my kids Put all the unknowns to the LHS and all the numbers to the RHS, and if you jump sides, change your sign, so for example, you have something like 5x + 4 = 2x + 16, solve for x, this is how you do it EVERY TIME 5x - 2x = 16 - 4 3x = 12 x = 12/3 = 4 No matter what your numbers are OR what SIGN is in front of them USE the same method and it works every time. Good Luck Regards Alex
