Question

is (-7, -2) a solution to this system of equations
3x - 11y = 1
3x - 14y = 7
yes no

Explanation:

Step1: Substitute \( x = -7 \), \( y = -2 \) into first equation

Substitute into \( 3x - 11y = 1 \):
\( 3(-7) - 11(-2) = -21 + 22 = 1 \).
Left - hand side (LHS) equals right - hand side (RHS) for the first equation.

Step2: Substitute \( x = -7 \), \( y = -2 \) into second equation

Substitute into \( 3x - 14y = 7 \):
\( 3(-7)-14(-2)=-21 + 28 = 7 \).
LHS equals RHS for the second equation.

Answer:

yes
