Explanation:
Given,
#-4(2x-1)=-6(x+2)-2#
Expand the brackets.
#-8x+4=-6x-12-2#
Simplify.
#-8x+4=-6x-14#
Subtract
#-8x+4color(white)(i)color(red)(-4)=-6x-14color(white)(i)color(red)(-4)#
#-8x=-6x-18#
Add
#-8xcolor(white)(i)color(red)(+6x)=-6xcolor(white)(i)color(red)(+6x)-18#
#-2x=-18#
Divide both sides by
#color(red)((color(black)(-2x))/(-2))=color(red)((color(black)(-18))/(-2))#
#color(green)(|bar(ul(color(white)(a/a)color(black)(x=9)color(white)(a/a)|)))#
