15% is the rate of discount
85% of 80 is 68
And 100-15= 85.
I can’t see the data did you forget to put it or like forget to put a picture???
Answer:
{x,y} = {115/17,-23/17}
Step-by-step explanation:
I believe its true.
Here, x - 2y = 14
x = 14 + 2y
Now, substitute this value into first equation,
4x + 6y = 0
4(14 + 2y) + 6y = 0
56 + 8y + 6y = 0
14y = -56
y = -56/14
y = -4
Substitute it into second equation,
x = 14 + 2(-4)
x = 14 - 8
x = 6
In short, Your Answer would be: (6, -4)
Hope this helps!
