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
