First, expand the terms on the right side of the inequality to eliminate the parenthesis:
6x - 3 <= (3 xx x) - (3 xx 1)
6x - 3 <= 3x - 3
Next, subtract color(red)(3x) and add color(blue)(3) to each side of the inequality to isolate the x term while keeping the inequality balanced:
6x - 3 - color(red)(3x) + color(blue)(3) <= 3x - 3 - color(red)(3x) + color(blue)(3)
6x - color(red)(3x) - 3 + color(blue)(3) <= 3x - color(red)(3x) - 3 + color(blue)(3)
(6 - 3)x - 0 <= 0 - 0
3x <= 0
Now, divide each side of the inequality by color(red)(3) to solve for x while keeping the inequality balanced:
(3x)/color(red)(3) <= 0/color(red)(3)
(color(red)(cancel(color(black)(3)))x)/cancel(color(red)(3)) <= 0
x <= 0
