Question

Workout the following divisions $\dfrac{(49x - 63)}{7}$
A. $7x + 9$
B. $7x - 9$
C. $7x - 6$
D. None

Answer 1

Hint: In this question we have to simply divide the equation with number seven. First, we have to divide the number $49x$ by 7 then we have to divide the number 63 by 7.for solving this question only the division part is important. Separate the equation first for simplifying the equation.

Complete step-by-step answer:
We have the equation $\dfrac{(49x - 63)}{7}$
First separate the equation in two parts
$49x,63$
We have to simply divide the two parts by 7
First, we have to divide the $49x$ by 7
= \[\dfrac{{49x}}{7}\]
$ = 7x$
Now we have to divide the number 63 by 7
$ = \dfrac{{63}}{7}$
$ = 9$
Join both parts as there is minus in the equation so, put the minus between the numbers
$ = 49x - 63$
Dividing the equation by 7 we get
$ = 7x - 9$
So, the answer is $7x - 9$

Option B is the correct option.

Note: We can solve this question without separating the parts like
= $\dfrac{{49x - 63}}{7}$
$ = 7x - 9$
We get the answer option B is the correct option here as well. Simple division is needed for solving the question. Students mostly make mistakes in the division part. For solving this question, you must know the multiple of seven. Students get confused between the x as there is no number or value given for the x. Do not forget to put the minus in between the numbers as the minus given in the equation.
