# 1

+1-Ax-B=0 Start with the given equation.


+1-Ax=B Add B to both sides.


+-Ax=B-1 Subtract 1 from both sides.


+x=%28B-1%29%2F%28-A%29 Divide both sides by -A.


+x=%281-B%29%2F%28A%29 Simplify.





# 2

3%2F%28x%2B2%29=5 Start with the given equation.


3=5%28x%2B2%29 Multiply both sides by x%2B2


3=5x%2B10 Distribute.


0=5x%2B10-3 Subtract 3 from both sides.


-5x=10-3 Subtract 5x from both sides.


-5x=7 Combine like terms on the right side.


x=%287%29%2F%28-5%29 Divide both sides by -5 to isolate x.


x=-7%2F5 Reduce.

Answer:

So the answer is x=-7%2F5


Which approximates to x=-1.4
