Question

tell whether the ordered pair (-2, 1) is a solution of the system of linear equations.
y = x + 3
y = -2x - 5
(-2, 1)
a solution of the system of linear equations.

Explanation:

Step1: Check first equation

Substitute \( x = -2 \), \( y = 1 \) into \( y = x + 3 \).
Left side: \( y = 1 \). Right side: \( -2 + 3 = 1 \). Both sides equal.

Step2: Check second equation

Substitute \( x = -2 \), \( y = 1 \) into \( y = -2x - 5 \).
Left side: \( y = 1 \). Right side: \( -2(-2) - 5 = 4 - 5 = -1 \). \( 1
eq -1 \).

Answer:

The ordered pair \((-2, 1)\) is not a solution of the system.
