Answer:
C. (2,-3) is a solution to the system of linear equations
Step-by-step explanation:
3x - y = 9
4x + y = 5
---------------add
7x = 14
x = 14/7
x = 2
3x - y = 9
3(2) - y = 9
6 - y = 9
-y = 9 - 6
-y = 3
y = -3
Answer:
Tina earned $11.5
Step-by-step explanation:
From the question, we are told that Tiana earns 2.50 less than twice what is earned by Add
let us have x as what is earned by Add
Thus, we have what is earned as 2x-2.5
Now Add, earned 6.50, so we want to know what Tina earned
That would be;
2(6.5) - 2.5
= 13-2.5
= 10.5
There not a answer for that
Here is the answer.
You just have to remember the given formula.
