Answer:
x =6
Step-by-step explanation:
[tex]3x-8(2x+3)= -6(2x+5)\\\\\mathrm{Expand}\:-8\left(2x+3\right):\quad -16x-24\\3x-16x-24=-6\left(2x+5\right)\\\\\mathrm{Add\:similar\:elements:}\:3x-16x=-13x\\-13x-24=-6\left(2x+5\right)\\\\\mathrm{Expand\:}-6\left(2x+5\right):\quad -12x-30\\-13x-24=-12x-30\\\\\mathrm{Add\:}24\mathrm{\:to\:both\:sides}\\-13x-24+24=-12x-30+24\\\\Simplify\\-13x=-12x-6\\\\\mathrm{Add\:}12x\mathrm{\:to\:both\:sides}\\-13x+12x=-12x-6+12x\\\\Simplify\\-x=-6\\\\\mathrm{Divide\:both\:sides\:by\:}-1\\[/tex]
[tex]\frac{-x}{-1}=\frac{-6}{-1}\\\\Simplify\\\\x =6[/tex]
