Solve the inequality. Expression solution set using interval notation and graph the solution set using a number line. -15x+3<_-3(4x-7)

Thats supposed to be a greater than or equal to sign lol

1 answer

-15x+3 >= -3(4x-7).
-15x+3 >= -12x+21.
-15x + 12x >= 21-3.
-3x >= 18.
X <= -6.

When multiplying or dividing an
inequality by a negative number,
the inequality sign should be reversed.
