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.
If you know matrix algebra, the process is simply to find the inverse for the matrix of coefficients and apply that to the vector of answers. If you don't: You solve these in the same way as you would solve a pair of simultaneous linear equations in two unknowns - either by substitution or elimination. For example, change the subject of one of the equations to express one of the variables in terms of the other two. Substitute this value into the other two equations. When simplified, you will have two linear equations in two variables.
To solve problems using elimination, start by rewriting the equations in standard form if they aren’t already. Next, manipulate the equations to make the coefficients of one variable opposites, allowing you to add or subtract the equations to eliminate that variable. Once one variable is eliminated, solve for the remaining variable and then substitute back to find the other. This method is particularly effective for systems of linear equations.

Quality does not normally play any part in linear equations.
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.
Linear Algebra is a branch of mathematics that enables you to solve many linear equations at the same time. For example, if you had 15 lines (linear equations) and wanted to know if there was a point where they all intersected, you would use Linear Algebra to solve that question. Linear Algebra uses matrices to solve these large systems of equations.
To solve linear equations, you always use the inverse operations
You simplify the brackets first and then you will have linear equations without brackets!

Because its linear and the equation is a problem to solve
The answer depends on whether they are linear, non-linear, differential or other types of equations.

multiply the whole equation by the number in the denominator
If you already know that x = -3 and y = 5 what linear equations are you wanting to solve?
