Question

# In an academic contest correct answers earn 12 points and incorrect answers lose 5points. In the final round, school A starts with 165 points and gives the same numberof correct and incorrect answers. School B starts with 65 points and gives no incorrect answers and the same number of correct answers as school A. The game ends with the two schools tied.ii)How many answers did each school get correct in the final round?

## The correct answer is: Hence, the school A gives 20 correct answers

### Answer: Step by step explanation: ○    Step 1:○    Solve equation: 165 + 12x - 5x = 65 + 12x                          165 + 12x - 5x = 65 + 12x                          165 + 7x = 65 + 12x                          165 - 65 = 12x - 7x                          100 = 5x                             = x                         20 = x Final Answer: Hence, the school A gives 20 correct answers.

A linear equation in one variable is an equation that has only one solution and is expressed in the form ax+b = 0, where a and b are two integers and x is a variable. 2x+3=8, for example, is a linear equation with a single variable. As a result, this equation has only one solution, x = 5/2.
¶The standard form of a linear equation in one variable is: ax + b = 0
Where,
The letters 'a' and 'b' are real numbers.
'a' and 'b' are both greater than zero.
