Answer:
y=7
x=-7
Step-by-step explanation:
2(-3x - 7y )= 2(-28)
3(2x+ 3y)=3(7)
-6x - 14y = -56
6x + 9y = 21
Add the two equations
-1(0x - 5y)= -1(- 35)
5y = 35
Divide both sides by 5
y=7
Substitution
6x + 9(7) = 21
6x + 63 = 21
Subtract 63 from both sides
6x = -42
Divide both sides by 6
x= - 7
Answer:
F
Step-by-step explanation:
By using the given information about the inverse relation, we will get:
- Equation: y = -28/x
- Solution: y = -14

How to get the relation between x and y?</h3>
First, we know that y varies indirectly with x, then we can write the relation as:
y = k/x.
Where k is a constant.
Then, we know that when y = 7, we have x = -4.
Replacing these we can find the value of k:
7 = k/(-4)
7*(-4) = k = -28
Then the relation between x and y is:
y = -28/x.
Now, we want to find the value of y when x = 2, then we just replace that in the above equation:
y = -28/2 = -14
So we have:
- Equation: y = -28/x
- Solution: y = -14

Answer:
-40
Step-by-step explanation:
13-2x = 93
-2x = 93-13
-2x = 80
x = -40
