6y-8= 4x+10

2x+7.8= 9.4

13= 5m-2

13.5-2m = 5m + 41.5

35= -1 -6m

8( y-1)= 4 (y + 4)

4( 5-r)= 3 (2r-1)

12(n-3)-5(n+2)= 2(n-4)+7

plz asap!!!!

thank u!!!!!!

Hi guys
I need to have a step by step solution way,I have the answers the weight percent of Cu2S in the Ore is 62.2% ,the weight Percent CuS in the Ore is 26.8 Percent.I need just Solution way

Copper metal can be prepared by roasting Copper Ore which can contain cuprite (Cu2S) and Copper (II) Sulfide.
Cu2S(s)+O2(g) then 2Cu(s)+SO2(g)
CuS(s)+O2 (g) then Cu(s)+SO2(g)
Suppose an Ore sample contains 11% impurity in addition to a mixture of CuS and Cu2S.Heating 100.0 gr of the mixture produces 75.4 gr of Copper metal with apurity of 89.5%.
What is the weight percent of CuS in the Ore?the weight percent of Cu2S?

He does not matter where the theory of the gravity of Newton if based, in which the bodies if attract reciprocamente with a force that was called mass; e each one is inversely proportional to the square of in the distance between them. I ask! This same gravity in the Land exists for the Sun, that only loses energies, but does not lose its gravitational forces of attraction for the bodies that had always kept its distancias? The American physicists say: The current theory is that the universe exists 92 billion years - and the sun converts 3.000.000 of tons of substance for energy each AS. The Brazilian physicists say: When the account of the mass becomes that the Sun loses, seems very, but relatively the mass of the sun, is only one minimum fraction. So minimum that its gravitational force practically remains unchanged during many millions of years. Tarcísio Brito says: that the Universe and finite in its dimension and the infinite in its time.

1) Solve. 10x – 0.62 = 9(x – 0.95)

2)Solve. 4(x + 2) – 3x = x – 6

3)Graph the solution set of x > with a line under it –7.

4)Solve. 6x + 4(3x – 2) = 6x + 2
