Question
one or both equations need to be modified before they can be combined using addition. select the variable to eliminate: x multiply the equation by -8x - 8y = -18 ------ -1 -------> 8x + 8y = 18 multiply the equation by 4x + y = -9 ------ -2 -------> + -8x - 2y = 18
Step1: Sumar las ecuaciones modificadas
Sumamos la ecuación \(8x + 8y = 18\) y \(-8x - 2y = 18\). Al sumar los términos con \(x\): \(8x + (-8x)=0\). Al sumar los términos con \(y\): \(8y+(-2y) = 6y\). Al sumar los términos constantes: \(18 + 18=36\).
Step2: Escribir la ecuación resultante
La ecuación resultante después de la suma es \(6y=36\).
