What is Simplifying?
Look carefully, the 1st step is veryyyyyy Long and complicated
and the final answer is veryyyyy short and Simple.
"Simple and Short make it Sweet"
[2(x + 5y) - 3(x-y)] - 7[3x-(x+6y)]
= [2x + 10y - 3x + 3y] - 7[3x - x - 6y]
= [2x - 3x + 10y + 3y] - 7[2x - 6y]
= [ -x + 13y ] - 14x + 42y
= - x + 13y - 14x + 42y
= 42y + 13y -14x -x
= 55y - 15x
CONCLUSION:
Basically, to simplify an equation you just need to understand the following
words in the bracket and you will master in just a few minutes!Look carefully, the 1st step is veryyyyyy Long and complicated
and the final answer is veryyyyy short and Simple.

= 42y + 13y -14x -x
= 55y - 15x
CONCLUSION:
Basically, to simplify an equation you just need to understand the following
"Inner to Outer, Left to Right" (Filomaths' mantra)
- Expansion Mantra: "Sign with Sign, No with No, Alpha with Alpha" (Modification)
- Arrangement Mantra: "x with x, x*2 with x*2, y with y and so on..." (Modification)
- Simplifying (Combination)
