Answer 2

Step-by-step explanation:

Given: $18 - 7n = - 3$

To find: Solve the equation.

Solution:

Step 1: Take 18 to RHS.

We know that in this operation sign of 18 is changed.

So,

$- 7n = - 3 - 18$

Step 2: Add the numbers of RHS.

As both have same sign, so addition will perform.

$- 7n = - 21$

Step 3: Cancel negative sign from both sides.

$7n = 21$

Step 4: Divide by 7.

$n = \frac{21}{7}$

$\bf n = 3$

Final answer:

Value of n is 3.
