Question

is (-5, -1) a solution to this system of equations?
y = -1
3x + y = 16
yes
no

Explanation:

Step1: Check first - equation

Substitute \(y=-1\) into \(y = - 1\). Since \(-1=-1\), the point satisfies the first equation.

Step2: Check second - equation

Substitute \(x=-5\) and \(y = - 1\) into \(3x + y=16\). We get \(3\times(-5)+(-1)=-15 - 1=-16
eq16\).

Answer:

no
