The correct option is option (d) . Using the "BODMAS" rule we can easily simply the expression. The simplest form of given expression is 42x- 27 ..
One of the best way to remember the order of operations is "BODMAS ".
The BODMAS rule follows the order of the BODMAS acronym, i.e.
B – Brackets, O – Order of powers or roots,
D – Division, M – Multiplication A – Addition, and S – Subtraction.
The BODMAS rule states that mathematical expressions with multiple operations need to be solved from left to right in the order of BODMAS
we have given expression is
7(6x - 4 ) + 1
first step, open the brackets by multiplying 7 with each term inside brackets without any change in position of x we get
7× 6x - 7×4 +1
=> 42x - 28 +1
Now , combine the same terms by addition or substraction (like terms means constant with constant, coefficient of x terms with coefficient of x ) we get ,
42x - 27
which is the required simplify form of given expression.
