Answer:

X = -5

y = 1

Step-by-step explanation:

plug in -3x - 14 for y

x + 4 ( -3x - 14) = -1

x - 12x - 56 = -1

-11x = 55

x = -5

plug in for x

-3(-5) - 14 = y

15 - 14 = y

y = 1

plug in and it proves equal

Y=6x+20 substitution​
Oksana_A [137]

Answer:

-10/3 or -3.33

Step-by-step explanation:

substitute 0 for y

0 = 6x + 20  

-20 = 6x + 20 - 20               subtract 20 on both sides  

-20 = 6x                               divide by 6 on each side

-20/6 = 6x/6

x = -20/6                             simplify

x =   -10/3
