Question

Solve using substitution.

–7x − 8y = 13
y = –6

(, )

Answer 1

The answer is (x,y)= (5, -6).

-7 x -8 x (-6) = 13
X=5

The possible solution of the system is the ordered pair (x, y)
(x,y)=(5, - 6)

(x, y) = (5, -6)
Check the solution

-7x5-8x1-6=13
-6=- 6
Simplify

13=13
-6=-6

Solution is (5,-6)

Answer 2

Answer: (5, -6)

Explanation:

Given the system of equations:

1. –7x − 8y = 13

2. y = –6

Substitute the value of y from equation 2 into equation 1:

–7x − 8(-6) = 13

–7x + 48 = 13

–7x = 13 - 48

–7x = -35

x = -35 / -7

x = 5

So, the solution is x = 5 and y = –6.
