The equation I would use to solve this is (l+5)+l=19 r=l+5 Total students=19
(l+5)+l=19-Write the equation 2l+5=19-Combine like terms 2l=14-Subtract five from both sides of the equation l=7-Divide both sides by two Therefore there are 7 left-handed students out of the 19
Since there are five more right handed students that left-handed you use the equation r=l+5 r=(7)+5-Substitute the value of l you found r=12
