Algebraic equations with two variables will need two equations to be able to solve it.
Then, you can solve it with either substitution, adding/subtracting them together, or graphing! Those are the basic steps...
For example:
An instance of substitution:
2x + 1 = y + 2
x + y = 3
You could isolate y in the second equation to equal
y = 3-x.
Then in the first equation, substitute y with what it equals to
2x + 1 = 3-x+2
Then you can solve for x!

Why is the word algebra in boolean algebra?
You have Boolean operators (such as AND & OR) on variables, rather than mathematical operations (+ - etc). The variables can only have one of two states (values) though (True/False, on/off, 1/0).
What are the letters in algebra called?
variables
What is y if 20x plus 5y 15?
It is not possible to solve one linear equation in two variables for either of the variables.
Why do you call it algebra?
you call it algebra because it has an unknown number which you have to solve for

Can you explain algebra?
Algebra is using variables such as x to solve a problem. One example is x+3=8 in which x equals 5.
Why do we need algebra?
Algebra is needed to solve any complex calculation involving an unknown variable. Everything from computer games to flying to the moon relies upon algebra to calculate variables required.
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.
Why are letters used in variables?
To understand the formulas and concepts in algebra very easily and also in order to solve the problem much efficiently
How do you do an algebra equation with two variables?
The answer depends on what exactly you mean by doing an equation!
