Answer 2

❁Required Solutions:

By using transposing method we can find the value of unknown given number.

❁Formimg Equation:

2x+9 = 13 .

❁Finding Equation value:

subtracting from both sides,

$2x + 9 - 9 = 13 - 9 = 4 \\ 2x = 4$

Dividing both sides,

$\frac{2x}{2} = \frac{4}{2} \\ = 2$

❁Final Answer:

$\fbox \red{thus \: x = 2 \: is \: the \: final \: answer}$

❁Note:

• An equation must be same side. (=) sign should be there
• If the side where not equal means that is not equal.
