Several methods exist, for example:
Add one equation to the other equation - or add multiples of each equation.
Example:
x+y = 5
2x-y = 10
Adding the equations results in:
3x = 15
Now you can solve for x; this is then replaced in one of the original equations.
Solve one equation for one variable. Substitute in the other equation. Example:
x+y = 5
2x-y = 10
Solve the first equation for x: x = 5 - y
Replace in the second equation: 2(5-y) - y = 10
Once again, you can solve for one variable, then replace that variable in one of the original equations.
Solve both equations for the same variable.
Example:
x+y = 5
2x-y = 10
Solve each equation for x:
Equation 1: x = 5 - y
Equation 2: 2x = 10 - y; x = 5 - y/2
Equate the right sides of both equations (this is valid, since they are both equal to x):
5 - y = 5 - y/2
It has two methods. One is substitution method,
and second one is elimination method

What is it called when you solve for two lines of algebraic equations simultaneousley?
Its called Simultaneous Equations
How do you solve simultaneous quadratic equations?
Graphically might be the simplest answer.
What did ABC computers do?
solve systems of up to 29 simultaneous equations.
How do you solve parallel equations?
Parallel lines never meet and so parallel equations do not have any simultaneous solution.
What does John Atanasoff electronic computer do?
Solve simultaneous equations of up to 29 variables.
What are simultaneous equation in maths?
Simultaneous equations are where you have multiple equations, often coupled with multiple variables. An example would be x+y=2, x-y=2. To solve for x and y, both equations would have to be used simultaneously.
Why inversion of matrix is usefull?
The most common use for inverted matrices is to solve a set of simultaneous equations.

How do you solve an equation with two variables?
By substitution or elimination of one of the variables which usually involves simultaneous or straight line equations.
9x-5y-4 equals 0 Solve for y?
Can't be done unless you have another equation with the same x and y. Then you would solve for simultaneous equations.
What are equations that have the same answer?
Simultaneous equations have the same solutions
When lines overlap in a system of equations?
Then they are simultaneous equations.
