Lets assume the lowest mark is = x
twice the lowest mark will be = 2x
given that twice the lowest marks plus seven is highest mark
so....
2x + 7 = 87
2x = 80
x = 80 / 2
x = 4p
hence the lowest marks is 40
twice the lowest mark will be = 2x
given that twice the lowest marks plus seven is highest mark
so....
2x + 7 = 87
2x = 80
x = 80 / 2
x = 4p
hence the lowest marks is 40

Problem:
The teacher tells the class that the highest marks obtained by a student in her class is twice the lower marks plus 7. The highest score is 87. What is the lowest score?
Solution:
To find the lowest score, we need to work backwards from the highest score and use the given information.
Step 1: Identify the given information:
- The highest score is 87.
- The highest score is twice the lower marks plus 7.
Step 2: Represent the given information mathematically:
Let's assume the lowest score to be 'x'.
According to the given information, the highest score is 87, which is twice the lowest score plus 7. So we can write this as an equation:
87 = 2x + 7
Step 3: Solve the equation for 'x':
To find the value of 'x', we need to isolate it on one side of the equation. We can do this by performing inverse operations.
Subtracting 7 from both sides of the equation, we get:
87 - 7 = 2x
80 = 2x
Dividing both sides of the equation by 2, we get:
x = 40
Step 4: Find the lowest score:
The lowest score is 40.
Answer:
The lowest score obtained by a student in the class is 40.
