Solve each inequality Write each solution set in interval no

Solve each inequality. Write each solution set in interval notation. 2x + 8 16 -2x - 2 1 + x 3(x + 5) + 1 5 + 3x

14) -3x - 8 <= 7

Adding 8 on both sides

==> -3x - 8+8 <= 7+8

==> -3x <= 15

divide by 3 on both sides

==> -3x/3 <= 15/3

==> -x <= 5

multiply by -1 on both sides

==> -1(-x) >= -1(5) (inequality sign changes when multiplied by negative number)

==> x >= -5

==> x belongs to [-5 , )
