Use distributive property in 2(3c - 5)+2(2c)
Which gives you 6c-10+4c then combine like terms which gives you 10c-10
There is no single solution but there is a group of solutions also known as the interval.
This can be written with an interval.
Hope this helps.

Answer:
the answer to this question is 2.4b
Answer:
2 CH4(g) + 4 O2(g) --> 2 CO2 (g)+ 4 H2O(g)
Step-by-step explanation:
The number are subscripts.
Now count the number of each kind of atom on the left and right side of the equation. Note, you have 4 H on the left and as written you have only 2 on the right. So add a coefficient-- a number in front of the formula.
CH4 +O2 ----- CO2 + 2 H2O
With the added coefficient in front of water, the number of hydrogens balance but the number of oxygens do not. There are only 2 oxygens on the left and a total of 4 oxygens on the right. A coefficient of 2 in front of oxygen on the left balances the equation.
