Answer 1

Answer:

please mark as brainliest

Step-by-step explanation:

2n+3=15

2n=15-3

2n=12

n=12/2=6

Answer 2

ANSWER:

n=6

$\rule{300}{2}$

EXPLANATION:

Here this is a question from linear equation, we have given an equation and we have to find value of variable n. To find the value of n we have to simplify the given equation.

So let's solve it step by step!

$\rule{300}{2}$

Given linear equation:

2n+3=15

$\rule{300}{2}$

To find:

Value of n

$\rule{300}{2}$

Solution:

→ 2n+3=15

Here when we transfer 3 from LHS to RHS we have to do additive inverse of 3.

→ 2n=15-3

$\rule{300}{2}$

Now subtract 3 from 15

→ 2n=12

$\rule{300}{2}$

Here both LHS and RHS have 2 as commen factor.

So let's subtract 2 from both sides.

→ n=6

So the value of n comes out to be 6.

$\rule{300}{2}$

ADDITIONAL INFORMATION:

What is additive inverse?

The changing of sign from -ve to +ve or +ve to -ve is called additive inverse.
