Question

1. -12x + 7 = 79 Please help me

Answer 1

Answer:

X=-6

Step-by-step explanation:

Answer 2

$- 12x + 7 = 79$

$- 12x = 79 - 7$

$- 12x = 72$

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

$x = - 6$

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

Which means :-

= -12 × -6 + 7 = 79

= 72 + 7 = 79

LHS = RHS

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