\left(a-1\right)\left(x+1\right)=\left(a+1\right)\times 3-\left(3-2a\right)
Variable a cannot be equal to any of the values -1,1 since division by zero is not defined. Multiply both sides of the equation by \left(a-1\right)\left(a+1\right), the least common multiple of a+1,a-1,a^{2}-1.
ax+a-x-1=\left(a+1\right)\times 3-\left(3-2a\right)
Use the distributive property to multiply a-1 by x+1.
ax+a-x-1=3a+3-\left(3-2a\right)
Use the distributive property to multiply a+1 by 3.
ax+a-x-1=3a+3-3+2a
To find the opposite of 3-2a, find the opposite of each term.
ax+a-x-1=3a+2a
Subtract 3 from 3 to get 0.
ax+a-x-1=5a
Combine 3a and 2a to get 5a.
ax+a-x-1-5a=0
Subtract 5a from both sides.
ax-4a-x-1=0
Combine a and -5a to get -4a.
ax-4a-1=x
Add x to both sides. Anything plus zero gives itself.
ax-4a=x+1
Add 1 to both sides.
\left(x-4\right)a=x+1
Combine all terms containing a.
\frac{\left(x-4\right)a}{x-4}=\frac{x+1}{x-4}
Divide both sides by -4+x.
a=\frac{x+1}{x-4}
Dividing by -4+x undoes the multiplication by -4+x.
a=\frac{x+1}{x-4}\text{, }a\neq -1\text{ and }a\neq 1
Variable a cannot be equal to any of the values -1,1.
\left(a-1\right)\left(x+1\right)=\left(a+1\right)\times 3-\left(3-2a\right)
Multiply both sides of the equation by \left(a-1\right)\left(a+1\right), the least common multiple of a+1,a-1,a^{2}-1.
ax+a-x-1=\left(a+1\right)\times 3-\left(3-2a\right)
Use the distributive property to multiply a-1 by x+1.

Use the distributive property to multiply a+1 by 3.
ax+a-x-1=3a+3-3+2a
To find the opposite of 3-2a, find the opposite of each term.
ax+a-x-1=3a+2a
Subtract 3 from 3 to get 0.
ax+a-x-1=5a
Combine 3a and 2a to get 5a.
ax-x-1=5a-a
Subtract a from both sides.
