Question

How many solutions does the system have?

x = -4y + 4
2x + 8y = 8

Answer 1

in the second equation

1) subtract 8y from both sides
2) divide both sides by 2

you will see that the second equation is a multiple of the other.

Answer 2

1 -4 4
2 8 -8

1 -4 4

0 16 0

so

y=0 and x=4

Answer 3

wow dude !!

\(\Large\color{blue}{ \bf x = -4y + 4 }\)
\(\Large\color{blue}{ \bf 2x + 8y = 8 }\)

\(\Large\color{blue}{ \bf x = -4y + 4 }\)
\(\Large\color{blue}{ \bf 2x =- 8y + 8 }\)

\(\Large\color{blue}{ \bf x = -4y + 4 }\)
\(\Large\color{blue}{ \bf x =- 4y + 4 }\)
