Double the second equation (multiply by 2)...
2(x-2y=10)
2x-4y=20
Bring in the second equation and add the equations:
(2x-4y=20)
+ (5x+4y=8)
7x=28
x=4
Plug in x into one of the equations to get y...
(4)-2y=10
-2y=6
y=-3
(6,-3)

Answer: It’s the third answer.
Step-by-step explanation:
There are 2.54 cm in one inch and 12 inches in one foot, so 2.54x12 = 1 foot. Multiply this by 2 to get 2 feet.
the answer of this question is (-2,2)

Answer:
She realised $12 from selling 8 bags of caramel corn
Step-by-step explanation:
Given
(8, 12)
Required
Determine what it means based on the available information
A function is always written as (x,y)
Where x is dependent on y
By comparison,
x = bags of caramel corn = 8
y = amount realised = 12
Assuming the currency is in dollars
Conclusively,
She realised $12 from selling 8 bags of caramel corn.
