Question

4. Solve the following equations and check your result in each case ix. -n/3=4​

Answer 1

Answer:

solution n= -12

Step-by-step explanation:

step 1-

Multiply all terms by the same value to eliminate fraction denominators

-n/3=4

3.-n/3=3.4

step 2-

Cancel multiplied terms that are in the denominator

3.-n/3=3.4

-n=3.4

step 3-

Multiply the numbers

-n=3.4

-n=12

step 4-

Divide both sides of the equation by the same term

-n=12

-n/-1=12/-1

and we get

n=-12

Answer 2

Answer:

12

Step-by-step explanation:

-n = 4

3

-n = 4×3 (Transposing 3 ,as it was in divide it will be in multiply)

-n = 12 (multiplying 4 and 3)

n= -12 (we knew -n is 12 so n will be it's opposite)

Checking:-

12 = 4 (putting the value of -n)

3

4 = 4 (cancelling 12 by 3)

Extra but important:-

If you want value of n then it is also given but in question it is only given -n so better solve till that
