I think the correct answer would be -8y = 13/2
I hope this helps you !

Step-by-step explanation:
25) Name the property used in each step:
i) Given.
ii) Distributive property.
iii) Commutative property.
iv) Distributive property.
v) Substraction.
vi) Law of signs, multiplication.
vii) Sum. Result.
11/3-4/3=7/3 or 2 1/3.
Note: 1 3/9 simplifies to 1 1/3.
Answer:
(2, - 3 )
Step-by-step explanation:
Given the 2 equations
2x - 3y = 13 → (1)
x + 2y = - 4 → (2)
Rearrange (2) expressing x in terms of y by subtracting 2y from both sides
x = - 4 - 2y → (3)
Substitute x = - 4 - 2y into (1)
2(- 4 - 2y) - 3y = 13 ← distribute and simplify left side
- 8 - 4y - 3y = 13
- 8 - 7y = 13 ( add 8 to both sides )
- 7y = 21 ( divide both sides by - 7 )
y = - 3
Substitute y = - 3 into (3) for corresponding value of x
x = - 4 - 2(- 3) = - 4 + 6 = 2
Solution is (2, - 3 )
