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

r+l=19-Finally check your answer
12+7=19
19=19
