# For Problems 31-44, solve each equation for the indicated variable. (Objective 2) y − 1 x − 3 = b − 1 a − 3 for y

To determine

To Solve:

Solve the equation for the indicated variable.

Explanation

Procedure used:

Rational expression, a quotient obtained by division of two polynomials in form of p(x,y)q(x,y) where p(x,y) and q(x,y) are polynomials in such a way that the variables x, y do not assume values such that q(x,y)=0.

If ab and cd are rational, then addition or subtraction of rational formed by making the denominator equal using LCD and perform the operation on the numerators as follows:

And,

Same algebra is used for rational expression.

Calculation:

The given equation is yâˆ’1xâˆ’3=bâˆ’1aâˆ’3
