If x + 4y = 18 and x − 4y = 2, then x = ?

x + 4y = 18 and x − 4y = 2

I would use substitution

add the 2 equations together

  x + 4y = 18

+ x − 4y = 2

2x + 0y = 20

2x = 20

divide each side by 2

2x/2 = 20/2

x = 10

x=1

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )

mean, 40.6
