Given the equation ![6x-3y=5.](https://tex.z-dn.net/?f=6x-3y%3D5.)
Check all options:
A.
, this means that
Substitute these numbers into the left side of the equation equation:
![6\cdot 9-3\cdot \dfrac{16}{3}=54-16=38\neq 5.](https://tex.z-dn.net/?f=6%5Ccdot%209-3%5Ccdot%20%5Cdfrac%7B16%7D%7B3%7D%3D54-16%3D38%5Cneq%205.)
This option is false.
B.
, this means that
Substitute these numbers into the left side of the equation equation:
![6\cdot 6-3\cdot (-3)=36+9=45\neq 5.](https://tex.z-dn.net/?f=6%5Ccdot%206-3%5Ccdot%20%28-3%29%3D36%2B9%3D45%5Cneq%205.)
This option is false.
C.
, this means that
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.](https://tex.z-dn.net/?f=6%5Ccdot%201-3%5Ccdot%20%5Cleft%28-%5Cdfrac%7B11%7D%7B3%7D%5Cright%29%3D6%2B11%3D17%5Cneq%205.)
This option is false.
D.
, this means that
Substitute these numbers into the left side of the equation equation:
![6\cdot (-2)-3\cdot \left(-\dfrac{17}{3}\right)=-12+17=5.](https://tex.z-dn.net/?f=6%5Ccdot%20%28-2%29-3%5Ccdot%20%5Cleft%28-%5Cdfrac%7B17%7D%7B3%7D%5Cright%29%3D-12%2B17%3D5.)
This option is true.
Answer: correct choice is D.
