You would solve them in exactly the same way as you would solve linear equations with real coefficients. Whether you use substitution or elimination for pairs of equations, or matrix algebra for systems of equations depends on your requirements. But the methods remain the same.
multiply the whole equation by the number in the denominator
False. While some techniques used for solving linear equations, such as isolating variables and cross-multiplying, can also be applied to rational equations, not all methods are applicable. Rational equations often require additional steps, such as finding a common denominator and checking for extraneous solutions, due to the presence of variables in the denominator. Thus, the approach to solving rational equations can be more complex than that for linear equations.
Yes, you can manipulate the equations before adding them to eliminate one variable. This can be done by multiplying one or both equations by a suitable coefficient so that the coefficients of one variable become opposites. Once the coefficients are aligned, you can add the equations together, resulting in the elimination of that variable, making it easier to solve for the remaining variable.

When the coefficients of either variable are different in a system of equations, you can use methods such as substitution or elimination to solve for the variables. If using elimination, you may need to multiply one or both equations by a factor to make the coefficients of one variable the same, allowing you to add or subtract the equations effectively. For substitution, isolate one variable in one equation and substitute it into the other. This will help you find the values of the variables.
Create a matrix of the coefficients of each equation. The solutions to the equations should make up the rightmost column of the matrix. Then, row reduce the matrix until you are able to rewrite the equations and solve them. The matrix should be a 4x5 matrix (4 rows and 5 columns) for four equations with four variables. This is known as a system of equations.
The method is the same.
A rational algebraic expression is the ratio of two polynomials, each with rational coefficients. By suitable rescaling, both the polynomials can be made to have integer coefficients.

To solve systems of equations using elimination, first align the equations and manipulate them to eliminate one variable. This is often done by multiplying one or both equations by suitable constants so that the coefficients of one variable are opposites. After adding or subtracting the equations, solve for the remaining variable, then substitute back to find the other variable. For inequalities, the same elimination process applies, but focus on determining the range of values that satisfy the inequalities.
