    Turn the sign into and equal sign 14+x=3 Subtract 14 from both sides x=-11

    a. \[-4x < -20\]\[\frac{ -4x }{ -4 } > \frac{ -20 }{ -4 }\]\[x > 5\]b.\[6x < 30\]\[\frac{ 6x }{ 6 } < \frac{ 30 }{ 6 }\]\[x < 5\]c\[\frac{ x }{ 4 } > \frac{ 5 }{ 4 }\]\[\frac{ 4x }{ 4 }> \frac{ 4 \times 5 }{ 4 }\]\[x > 5\]d. \[\frac{ -3x }{ 5 } < -3\]\[\frac{ 5 \times -3 x }{ -3 \times 5 } > \frac{ 5 \times -3 }{ -3 }\]\[x > 5\]
