Answer:

Step-by-step explanation:
So we have:

And we want to solve for x.
To do so, let's remove the fractions. We can multiply both sides by the LCM of a and b, which is ab. So:

On the left, distribute. On the right, multiply:

Simplify:

Now, factor out an x on the left:

Divide both sides by (b+a):

And we're done!
