Systems of Linear Equations

y = 5

-3x + 4y = 8

After substituting Equation 1 to Equation 2, what equation will I get?

• -3x + 4y(5) = 8

• -3(5) + 4y = 8

• -3x + 4(5) = 8

• -3x(5) + 4y = 8

y = 5

-3x + 4y = 8

What is the value of y in the given system of linear equation?

• y = -6

• y = 6

• y = -2

• y = 2

y = 2x

-6x + 3y = 16

After substituting Equation 1 to Equation 2, what equation will I get?

• -6(2x) + 3y = 16

• -6x + 2x = 16

• -6x + 3(2x) = 16

• 6x + 2x = 16

y = 2x

x + y = 9

What is the value of x in the given systems of linear equations?

• x = 6

• x = 3

• x = -3

• x = -6

y = -3x + 4

y = 4x - 10

After substituting Equation 1 to Equation 2, what equation will I get?

• 4x - 3x = 4 - 10

• -3x + 4 = 4x - 10

• y = 4(-3x + 4) - 10

• y = -3(4x - 10) + 4

y = -3x + 4

y = 4x - 10

What is the value of x in the given systems of equation?

• x = -2

• x = 2

• x = 4

• x = -4
