### Systems of Linear Equations

The statement explains why the ordered pair is a solution to the system of equations. Is the statement true or false?

True
False

The ordered pair [tex]\((-3, -6)\)[/tex] is a solution for the first equation, and it is a solution for the second equation. Therefore, [tex]\((-3, -6)\)[/tex] is a solution to the system of equations.

[tex]\[
\begin{array}{l}
-4x + y = 6 \\
5x - y = 21
\end{array}
\][/tex]



Answer :

To determine whether the ordered pair [tex]\((-3, -6)\)[/tex] is a solution to the given system of equations, we need to check if it satisfies both of the equations:

1. [tex]\(-4x + y = 6\)[/tex]
2. [tex]\(5x - y = 21\)[/tex]

Step-by-Step Verification

Equation 1: [tex]\(-4x + y = 6\)[/tex]

1. Substitute [tex]\(x = -3\)[/tex] and [tex]\(y = -6\)[/tex] into the equation.
[tex]\[ -4(-3) + (-6) = 6 \][/tex]

2. Simplify the left-hand side:
[tex]\[ 12 - 6 = 6 \][/tex]

3. Check if the left-hand side equals the right-hand side:
[tex]\[ 6 = 6 \][/tex]

The first equation is satisfied by the ordered pair [tex]\((-3, -6)\)[/tex].

Equation 2: [tex]\(5x - y = 21\)[/tex]

1. Substitute [tex]\(x = -3\)[/tex] and [tex]\(y = -6\)[/tex] into the equation.
[tex]\[ 5(-3) - (-6) = 21 \][/tex]

2. Simplify the left-hand side:
[tex]\[ -15 + 6 = -9 \][/tex]

3. Check if the left-hand side equals the right-hand side:
[tex]\[ -9 \neq 21 \][/tex]

The second equation is not satisfied by the ordered pair [tex]\((-3, -6)\)[/tex].

Conclusion:

Since the ordered pair [tex]\((-3, -6)\)[/tex] satisfies the first equation but does not satisfy the second equation, it is not a solution to the entire system of equations. Therefore, the statement is false.
