Solving Systems of Equations

The video tutorial explains how to solve a system of equations using the elimination method. It begins by introducing the concept of elimination, followed by rearranging and multiplying equations to eliminate variables. The tutorial then demonstrates adding equations to solve for the variable X and concludes by substituting to find the value of Y. The solution point is determined to be (2, 0).

What is the first step in solving a system of equations using the elimination method?

• Multiply both equations by the same number

• Eliminate a variable by adding the equations

• Subtract one equation from the other

• Divide both equations by a common factor

Why is the first equation rearranged in the elimination process?

• To simplify the coefficients

• To make it easier to multiply

• To make it easier to look at

• To eliminate the constant term

What is the purpose of multiplying the second equation by 2?

• To eliminate the constant term

• To eliminate the X variable

• To make the coefficients of Y equal

• To simplify the equation

After adding the equations, what is the resulting equation for X?

• -1x = -22

• 1x = 22

• x = -22

• x = 22

What is the value of X at the solution point?

• 3

• 2

• 1

• 0

Which equation is used to find the value of Y after determining X?

• 20y - 7x = -4

• 10y = 4 - 4

• 2x + 4y = 8

• 10y + 4 = 2x

What is the solution point of the system of equations?

• (0, 0)

• (0, 2)

• (2, 0)

• (2, 2)
