Isolate one of the variable using inverse operations. Then solve.
Example: 2x + 4y = 0 --subtract 4y>> 2x = -4y --divide by -4>> -1/2x = y --plug in your variable -->>

Solve the equation 12x-8y-16?
To start with, it is not an equation - there is no equality sign. You need 2 independent equations to solve when you have two unknowns, x and y.
What is the answer to f equals -8c plus 55?
It is not possible to solve a linear equation in two unknowns without knowing one of them.
What is -3y equals -x-7?
4
How do you solve -2x plus 4y equals 8?
You cannot solve one equation in two unknowns.
What is a system of linear equations in two variables?
They are a set of equations in two unknowns such that any term containing can contain at most one of the unknowns to the power 1. A system of linear equations can have no solutions, one solution or an infinite number of solutions.

What are 2 symbolic techniques used to solve linear equations and which is better?
There are more than two methods, and of these, matrix inversion is probably the easiest for solving systems of linear equations in several unknowns.

How do you solve 3w plus 7 equals x?
You can't solve it - you only have one equation and two unknowns. You need 2 equations to solve this.
How do you solve a system of equation with 3 equations and 3 variables?
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.
