Question

How is everyone's day going? Mine is okay can u help me on this question?

Answer 1

Answer:

x = 2 and y = 7

Step-by-step explanation:

We are given two equations:

1.      8x + y = 23

2. −10x  - y = −27

By adding both equations with each other we get:

(1.+2.) -2x = -4

Which can be reduced to:

(1.+2. : (-2)) x = 2

We can insert x in Equation 1. (or 2) and get:

8*2 + y = 23

16 + y = 23         [-16 on both sides]

y = 7

Resulting in x = 2 and y = 7 as a possible solution for this system.

Answer 2

Answer:

Step-by-step explanation:

8x + y = 23

-10x - y = -27

-2x = -4

x = 2

8(2) + y = 23

16 + y = 23

y = 7

(2, 7)
