Answer:

x= -10

Explanation:


2(x + 3) = x-4 \\ Solve by distributing: \\ 2x+2\cdot3=x-4 \\Simplify the arithmetic: \\ 2x+6=x-4 \\ 2x+6=x-4 \\ 2x+6-x=x-4-x \\ 2x-x+6=x-4-x \\ 1x+6=x-4-x \\ x+6=x-4-x \\ x+6=x-x-4 \\ x+6=-4 \\ x+6=-4 \\ x+6-6=-4-6 \\ x=-4-6 \\ x=-10

Answer:

2(x + 3) = x - 4

<=> 2x + 6 = x - 4

<=> 2x - x = -4 - 6

<=> x = -10
