Question

7. Solve the following equations and check the answer: 1. -2(n+3)=8​

Answer 1

Step-by-step explanation:

-2n+6=8

-2n=6-8

-2n=-2

n=1

Answer 2

Answer:

Hence we get value of n$=-7$

Step-by-step explanation:

In accordance with the information provided in the question,

We have find the value of the supplied expression in the above question.

Given the data in question -2(n+3)=8​

Arrange the equation and multiply with -2 into(n+3)

$-2n-6=8$

We have find the value of n in above equation

Now adding both side by 6 we get,

$-2n-6+6=8+6$

Simplifying further we get,

$-2n=14$

Now divide both side by 2 we get,

$\frac{-2n}{2} =\frac{14}{2} \\-n=7$

Shifting -ve sign from LHS to RHS we get the value of n as follow,

$n=-7$

Now check the equation and putting the value of n$=-7$

We get,

$-2n-6=8\\-2\times (-7)-6=8\\14-6=8\\8=8$

So, LHS=RHS
