- 12x + 7 = 79

- 12x = 79 - 7

- 12x = 72

x =  \frac{ \:  \: \:  72}{-12}

x =  - 6

Let us check whether we have found out the correct value of x or not by placing -6 in the place of x .

<h3>Which means :-</h3>

= -12 × -6 + 7 = 79

= 72 + 7 = 79

<h3>LHS = RHS</h3>

Therefore , 12 × -6 + 7 = 79 , ( x = - 6 ) .
