We can solve the equation by adding the numbers, finding a common denominator, combining multiplied terms into a single fraction, combining fractions with common denominator, multiplying the numbers, combining like terms, rearranging terms, eliminating fraction denominators, cancelling multiplied terms that are in the denominator, multiplying the numbers, adding/subtracting to both sides, simplifying, dividing both sides of the equation by the same factor, and simplifying.

The final answer it gives is
$$x=-(322)/(5)$$

Add the numbers:


$$83+x+(x)/(14)=14$$

Find common denominator:


$$(14)/(14) \cdot 83+(14)/(14)x+(x)/(14)=14$$

Combine multiplied terms into a single fraction:


$$(14 \cdot 83)/(14)+(14x)/(14)+(x)/(14)=14$$

Combine fractions with common denominator


$$(14 \cdot 83+14x+x)/(14)=14$$

Multiply the numbers


$$(1162+14x+x)/(14)=14$$

Combine like terms:


$$(1162+15x)/(14)=14$$

Rearrange terms:


$$(15x+1162)/(14)=14$$

Eliminate fraction denominators


$$14 \cdot (15x+1162)/(14)=14 \cdot 14$$

Cancel multiplied terms that are in the denominator


$$15x+1162=14 \cdot 14$$

Multiply the numbers:


$$15x+1162=196$$

Add/subtract to both sides


$$15x+1162-1162=196-1162$$

Simplify:


$$15x=-966$$

Divide both sides of the equation by the same factor:


$$(15x)/(15)=(-966)/(15)$$

Simplify:


$$x=-(322)/(5)$$


$$x=-(322)/(5)$$
