Question

Here is a system of linear equations: y= x+4 y= -3x-8

What is the solution to the system of equations shown?
A) (-3,1)
B) (1,-3)
C) (-1,-5)
D) (-5,-1)

Answer 1

• A) (-3,1)

Explanation:

Given system of linear equations:

• y= x+4
• y= -3x-8

---

• x + 4 = -3x - 8
• x + 3x = - 8 - 4
• 4x = -12
• x = -3

Then

• y =-3 + 4 = 1

Solution is (-3, 1)

Correct option is A
