2(x + 4)= -5 + 1 what is this answer

fiasKO [112]

Answer:

$x=-6$

Step-by-step explanation:

Given Equation:

$2(x + 4)= -5 + 1$

Solving the Equation for 'x':

$2(x + 4)= -4$

$2(x) + 2(4)= -4\\$

$2x+8=-4$

Subtracting '8' both sides:

$2x=-4-8$

$2x=-12$

Dividing by '2' both sides:

$x=-12/2\\$

$x=-6$

The Solution for the equation is: $x=-6$
