Set up equation and solve.

The teacher tells the class that the highest marks obtained by a student in her

class thrice the lowest mark minus 6. The highest score is 90. What is the lowest

score?
explain with statement​

Answer 1

highest mark = 3( lowest mark ) -6

90 = 3( lowest mark ) -6

96 = 3( lowest mark )

so,

lowest mark = 32
