"two less than 3/2 of a number (x) is no more than 5 1/2" 3/2x-2</5 1/2 (</ means less than or equal to) simplify 1.5x-2 </5.5 +2 both sides 1.5x</7.5 ÷1.5 both sides x</5 circle is closed arrow is to the left (1st number line )
"the sum of two times a number (x) and -2 is at least 8" 2x+-2>/8 (>/ means greater than or equal to) 2x-2>/8 +2 both sides 2x>/10 ÷2 both sides x>/5 circle is closed arrow is to the right (4th number line)
"seven subtracted from 4 times a number (x) is more than 13" 4x-7>13 +7 both sides 4x>20 ÷4 both sides x>5 circle is open arrow is to the right (2nd number line)
"four added to 3 times a number (x) is less than 19" 3x+4 <19 -4 both sides 3x <15 ÷3 both sides x <5 circle is open arrow is to the right (3rd number line)
