Given a system of three linear equations, the student will solve the system with a unique solution.

The premise of this problem is simple - young scholars must find three whole numbers with three different sums when they are added in pairs. To do this, they set up a system of linear equations in three variables. Aligns with A-REI.C.6.

Three examples are used to demonstrate solving a system of linear equations algebraically using addition and subtraction. The examples cover different situations that occur with the coefficients of the variable terms. Includes several...
