# 1

8x-3=7x%2B2 Start with the given equation.


8x=7x%2B2%2B3 Add 3 to both sides.


8x-7x=2%2B3 Subtract 7x from both sides.


x=2%2B3 Combine like terms on the left side.


x=5 Combine like terms on the right side.


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

Answer:

So the solution is x=5
=======================================================
# 2

-36%2B2w=-8w%2Bw Start with the given equation.


-36%2B2w=-7w Combine like terms on the right side.


2w=-7w%2B36 Add 36 to both sides.


2w%2B7w=36 Add 7w to both sides.


9w=36 Combine like terms on the left side.


w=%2836%29%2F%289%29 Divide both sides by 9 to isolate w.


w=4 Reduce.

Answer:

So the solution is w=4
