Understanding SPLDV

The video tutorial introduces the concept of Sistem Persamaan Linear Dua Variabel (SPLDV), explaining its general form and how it is a combination of two linear equations with one solution. It covers four methods to solve SPLDV: substitution, elimination, a combination of both, and graphical representation. An example is provided to demonstrate the substitution method, showing step-by-step how to find the values of x and y.

What does SPLDV stand for?

• System of Parallel Linear Double Variables

• System of Linear Equations with Two Variables

• System of Linear Equations with Three Variables

• System of Parallel Linear Dual Variables

Which of the following is a general form of SPLDV?

• AX + BY = C and PX + Q = R

• AX + BY = C and PX + QY = R

• AX + BY = C and PX + Y = R

• AX + BY = C and X + QY = R

Which method is NOT typically taught in middle school for solving SPLDV?

• Elimination

• Matrix

• Substitution

• Graphical

Which method combines substitution and elimination?

• None of the above

• Combination

• Graphical

• Matrix

What is the first step in the substitution method?

• Graph the equations

• Solve one equation for one variable

• Add the equations together

• Multiply the equations

In the example problem, what is the value of x?

• 3

• 2

• 1

• 4

In the example problem, what is the value of y?

• 4

• 3

• 2

• 1

What is the solution set for the example problem?
