My teacher help me with this math question but he didn't have enough time to explain it please help me

it's about substitution

y= x-8
y= -1/3x-4

x-8= -1/3x-4

1/3x= -4+8

this is the part I don't understand. Out of nowhere he got
4/3x = 4
can you please explain to me how my teacher got this? Thanks

both at 0 Celcius. The reaction is 2Na (s) + 2H2O(l) yields 2NaOH(aq) + H2(g) Triangle H = -368 kJ

Will the ice melt?Assuming that the final mixture has a specific heat capacity of 4.18 J/g x Celcius calculate the final temperature. the enthalpy fusion of ice is 6.02 Kj/mol

The design i was thinking about was a half oval (with 4 arches), with the open end down, and the pyramid built around it. The design should be structurally sound, and the construction materials used are only stone (like the egyptians). No current-day technologies can be used. Thanks for the help.
