# 1

3n-5%2B4n=6n-12 Start with the given equation.


7n-5=6n-12 Combine like terms on the left side.


7n=6n-12%2B5 Add 5 to both sides.


7n-6n=-12%2B5 Subtract 6n from both sides.


n=-12%2B5 Combine like terms on the left side.


n=-7 Combine like terms on the right side.


----------------------

Answer:

So the solution is n=-7


========================================================================

# 2

10=5x-2-4x Start with the given equation.


10=x-2 Combine like terms on the right side.


0=x-2-10 Subtract 10 from both sides.


-x=-2-10 Subtract x from both sides.


-x=-12 Combine like terms on the right side.


x=%28-12%29%2F%28-1%29 Divide both sides by -1 to isolate x.


x=12 Reduce.


---------------------

Answer:

So the solution is x=12

3n-5+4n=6n-12 ...
---
7n-5 = 6n-12
---
n = -7
-------------------
10 = 5x-2-4x
---
10 = x -2
---
x = 12
