Question

simplify the expression 6x +5 (X-2) and find the value. if x =2
​

Answer 1

Answer:

12

Step-by-step explanation:

=6(2) + 5(2-2)

=12+5(0)

=12+0

=12

Answer 2

$\large\sf\underline{Given\::}$

Expression :

• $\sf\:6x+5(x-2)$

Value of x is given as 2 .

‎

$\large\sf\underline{To\:find\::}$

• Value of the given expression

‎

$\large\sf\underline{Understanding\:the\:concept\::}$

In this question we are given an expression which consists a variable x and we are also given the value of the variable x as 2 . We are asked to find the value of the expression. It's very simple we just need to substitute the value of x in the expression. Doing so we will get the value of the expression. Let's proceed !

‎

$\large\sf\underline{Solution\::}$

$\sf\:6x+5(x-2)$

• Substituiting the value of x as 2

$\sf:\implies\:6(2)+5(2-2)$

• Doing simple calculations following BODMAS

$\sf:\implies\:6 \times 2 +5(0)$

$\sf:\implies\:12 +5 \times 0$

$\sf:\implies\:12 +0$

$\small{\underline{\boxed{\mathrm\red{:\implies\:12}}}}$ ⍟

$\large\sf\underline{Know\:More\::}$

BODMAS rule states that in an expression containing multiple arithmetic operations , there is an order in which they are to be solved .

The full form of BODMAS is :

• B - firstly expression in brackets must be simplified

• O - secondly order of exponents is simplified

• D - Thirdly division is done

• M - Fourthly multiplication must be done

• A - Fifthly addition of the expression

• S - Lastly subtraction must of done.
