Answer:
The values of a and b are
Option c)
Step-by-step-explanation:
The given equations are
ax + by = 3ab &
We have given that x = 1 and y = - 3.
By substituting these values in first equation, we get,
ax + by = 3ab
⇒ a * 1 + b * - 3 = 3ab
⇒ a - 3b = 3ab
⇒ a = 3ab + 3b
Now, by substituting the values in second equation,
Now, by substituting this value in equation ( 1 ),
∴ The values of a and b are
