For this case we have the following system of equations:
Equating the equations we have:
Adding 3x to both sides of the equation:
Subtracting 9 from both sides of the equation:
Dividing between -3 on both sides of the equation:
We look for the value of "and":
Thus, the solution of the system is (2, -3)
Answer:
(2, -3)
The cat is not hungry, or doesn't like the can of tuna food, which is why they refused to eat it when it was given to them.
Try to give the cat the food again and see their reaction, if that fails, try to give the cat other foods and note the reaction to determine if the cat just doesn't like the tuna in a can or just wasn't hungry at the moment.
twenty eight plus the product of five and a number
28 + 5n
28 + 5(4.2)
28 + 21

Substitute the value of 2nd equation into first equation,
3x - 6 = 2x - 3
3x - 2x = -3 + 6
x = 3
Then, substitute it in first equation,
y = 2(3) - 3
y = 6 - 3 = 3
In short, Your Answer would be: (3, 3)
Hope this helps!
