solve the equation below and show steps in work
1/3(12+x)=-8(6-x)

%281%2F3%29%2812+%2B+x%29+=+-+8%286+-+x%29
%2812+%2B+x%29%2F3+=+-+8%286+-+x%29
%2812+%2B+x%29%2F3+=+-+48+%2B+8x
3%28-+48+%2B+8x%29+=+12+%2B+x%29 ------- Cross-multiplying
-+144+%2B+24x+=+12+%2B+x%29
24x+-+x+=+12+%2B+144
23x = 156
highlight_green%28x+=+156%2F23%29
