Explanation:
Given,
#x+8-1>x/3#
Simplify the left side.
#x+7>x/3#
Multiply both sides by
#color(red)(3(color(black)(x+7)))>color(red)(3(color(black)(x/3)))#
Simplify.
#3x+21>x#
Subtract
#3xcolor(white)(i)color(red)(-3x)+21>xcolor(white)(i)color(red)(-3x)#
#21> -2x#
Divide both sides by
#color(red)(color(black)(21)/-2)> color(red)((color(black)(-2x))/-2)#
#x<-21/2#
Since you divided by a negative number, flip the inequality sign.
#x> color(green)(|bar(ul(color(white)(a/a)color(black)(-21/2)color(white)(a/a)|)))#
