Determine the ordered pair that satisfies the equation, 6x - 3y = 5.
Kazeer [188]

Given the equation 6x-3y=5.

Check all options:

A. \left(9,\dfrac{16}{3}\right), this means that x=9, y=\dfrac{16}{3}. Substitute these numbers into the left side of the equation equation:

6\cdot 9-3\cdot \dfrac{16}{3}=54-16=38\neq 5.

This option is false.

B.  \left(6,-3\right), this means that x=6, y=-3. Substitute these numbers into the left side of the equation equation:

6\cdot 6-3\cdot (-3)=36+9=45\neq 5.

This option is false.

C.  \left(1,-\dfrac{11}{3}\right), this means that x=1, y=-\dfrac{11}{3}. Substitute these numbers into the left side of the equation equation:

6\cdot 1-3\cdot \left(-\dfrac{11}{3}\right)=6+11=17\neq 5.

This option is false.

D.  \left(-2,-\dfrac{17}{3}\right),  this means that x=-2, y=-\dfrac{17}{3}. Substitute these numbers into the left side of the equation equation:

6\cdot (-2)-3\cdot \left(-\dfrac{17}{3}\right)=-12+17=5.

This option is true.

Answer: correct choice is D.

Furkat [3]

Answer:

2x^{2} + 4x +2

x × 2 is 2x

1 × 2x is 2x
