Question

Solve the system of equations using the substitution method. -x − 2y = 0 y = -8x (x, y) = ( , )

Answer 1

Answer:

$= { \tt{(0, \: 0)}}$

Step-by-step explanation:

Let:

${ \bf{ - x - 2y = 0 - - - (a)}} \\ { \bf{y = - 8x - - - (b)}}$

Substitute for y in equation (b) to equation (a):

${ \tt{ - x - 2( - 8x) = 0}} \\ { \tt{ - x + 16x = 0 }} \\ { \tt{x = 0}}$

Also, y = 0
