Hope you’re doing well.
Our today’s topic is
Brackets :How to use in equation solution
Here I’m going to explain
- what If one don’t place brackets at right positions while solving any equation consisting one or more Functions?
- what changes comes for not placing brackets?
- what happens if brackets placed at right place?
So without wasting time I’m starting,
suppose an equation is given
5x+ 4x =9x
5x+ -4x =9x,-9x , 1x, -1x
this creates confusion to some learners that from which function the equation will be operated,
so this should be
5x+(-4x) = 5x -4x = 1x or x
22+ 6 -8 ×-7 …..?????
this should be written correctly first i.e.
22 + 6 – 8 × (-7)
apply Bodmas rule
22 + 6 – -56
again it should be written correctly
22 + 6 – (-56)
22 + 6 + 56
and in algebra if the equation is,
3y + 5 × -x – 6÷ -3 …😒😓
quite confusion ha…!!!
OK, see below,
3y + 5× (-x) -6 ÷(-3)
3y -5x + 6/3
3y – 5x + 2.
must read tutorials:
Q. Divide 6x + -4x – 3y by 3.
if we write the above statement like
6x +(-4x) -3y ÷3
then it is totally wrong as instead of the equation only last term i.e. -3y is seems to be divided by 3,
so, we should place suitable Brackets
[ 6x +(-4x) -3y ] / 3
now this is explaining itself that the whole equation is divided by 3.
[ 6x -4x -3y] /3
[ 2x -3y ] /3
this is it.
I hope this tutorial of importance of brackets in math, remain helpful for you.
