Question
is (5, 6) a solution to this system of equations?
20x - 16y = 4
6x + 19y = -5
yes
no
Step1: Comprobar la primera ecuación
Sustituir \( x = 5 \) y \( y = 6 \) en \( 20x - 16y = 4 \):
\( 20(5) - 16(6) = 100 - 96 = 4 \). Esta es cierta.
Step2: Comprobar la segunda ecuación
Sustituir \( x = 5 \) y \( y = 6 \) en \( 6x + 19y = -5 \):
\( 6(5) + 19(6) = 30 + 114 = 144
eq -5 \). Esta es falsa.
