Linear Equations in Two Variables (Part 2)

Why is the solution 13 2/3 not feasible in the context of the problem?

• Because it results in a negative score.

• Because it involves a fraction, which is not possible in scoring.

• Because it exceeds the maximum score limit.

• Because it results in a zero score.

What is the result when substituting the values 11 and 2 into the equation?

• 20 plus 8 equals 30

• 20 plus 8 equals 28

• 22 plus 6 equals 28

• 22 plus 6 equals 30

What method is used to find solutions to equations in two variables?
