B. 3 because 12+ 9 = 21 then (4 + 3)x = 7x do you divide 7 by 21 and it’s x = 3 (hope this makes sense)

Answer: B(3)

Explanation: 12+9=21 so since 4+3 only equals 7, you plug in x as 3... since 7x3 is 21 that helps make the statement true bc both equations are equal.

1)\qquad5(x+3)=5x+15\\\\2)\qquad x+5(x+3)=x+5x+15=6x+15\\\\3)\qquad2[x+5(x+3)]=2(6x+15)=12x+30\\\\4)\qquad x-2[x+5(x+3)]=x-(12x+30)=x-12x-30=-11x-30\\\\5)\qquad3\{x-2[x+5(x+3)]\}=3(-11x-30)=-33x-90\\\\6)\qquad8+3\{x-2[x+5(x+3)]\}=8+(-33x-90)=-33x-82
