Answer 1

Answer:

Choice A,B and D are selected.

Step-by-step explanation:

To find : Select all the equations where n=6?

Solution :

Choice A : $4=10-n$

Solving the equation,

$n=10-4$

$n=6$

It is selected.

Choice B : $3=\frac{n}{2}$

Solving the equation,

$3\times 2=n$

$n=6$

It is selected.

Choice C : $12=n+7$

Solving the equation,

$n=12-7$

$n=5$

It is not selected.

Choice D : $8n=48$

Solving the equation,

$n=\frac{48}{8}$

$n=6$

It is selected.

Choice E : 5+n=8

Solving the equation,

$n=8-5$

$n=3$

It is not selected.

Therefore, Choice A,B and D are selected.
