Solutions 

Let's solve for a.

a/ax−1+b/bx−1=a+b

Step 1: Flip the equation.

a+b=2x−2

Step 2: Add -b to both sides.

a+b+−b=2x−2+−b

a=−b+2x−2

Answer:

a=−b+2x2

Let's solve for b.

a/ax−1+b/bx−1=a+b

Step 1: Flip the equation.

a+b=2x−2

Step 2: Add -a to both sides.

a+b+−a=2x−2+−a

b=−a+2x−2

Answer:

b=−a+2x2

Let's solve for x.

a/ax−1+b/bx−1=a+b

Step 1: Add 2 to both sides.

2x−2+2=a+b+2

2x=a+b+2

Step 2: Divide both sides by 2.

 \frac{2x}{2}   \frac{a+b+2}{2}

x=1/2a+1/2b+1

Answer:

x=1/2a+1/2b+1
