Answer:
This is more of a computer kind of thing, but try clicking the next thing at the bottom.
Step-by-step explanation:
❄️
We are given –
- And also value of y's given. So, just put the value of y in the given equation.
___________________________________

- Henceforth, value of x is 7.
_______________________________________
The domain of the function is x ≤ 6.88
The domain of the function is y ≤ 20
<h3>Domain and Range</h3>
- These are input and output values for which the function exists
Given the function of x expressed as:
y = 3.5x + 2.8
The domain occurs at the point where 3.5x + 2.8 ≤ 20
3.5x ≤ 20 - 2.8
3.5x ≤ 17.2
x ≤ 6.88 - Domain
This given the domain of the function.
The range of the function is the point where y ≤ 20

Answer:
The ordered pair that satisfies the equation is (7, -1)
Step-by-step explanation:
In order to find this, we can solve by subtracting. Start by stacking the two equations on top of one another and subtracting like terms.
3x + 3y = 18
(-) 2x + 3y = 11
--------------------
x = 7
Now that we have the value for x, we can plug in to either equation to find y.
2x + 3y = 11
2(7) + 3y = 11
14 + 3y = 11
3y = -3
y = -1
