You should probably combine like terms. For example, look below for an explanation: 2x - 3 = 4x + 5 + 3 + 3 ----------------- 2x = 4x + 8 -4x -4x ----------------- -2x = 8 ---- --- -2 -2 ------------------ x = -4

How do you solve algebra with two variables?
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 is y if 20x plus 5y 15?
It is not possible to solve one linear equation in two variables for either of the variables.
How do you solve an equation with two different variables on one side?
You decide to solve for one of the variables, for example, for "y". What exactly you do would depend on how the variables are related. For example, if you have:x + y = 5 and you want to solve for "y", you subtract "x" on both sides. If you have a product, such as: xy = 10 you divide both sides by "x".
What does product mean in college algebra?
Product means the answers when two variables are multiplied together. Such as, 4X3 the product would be 12.
How do you solve 5-b equals 2t algebra?
It is not possible to solve a single linear equation in two unknown variables (b and t).
What is the meaning of excluded values when used to solve algebra two problems?
excluded means to set aside. excluded values are the values set aside just for these problems and no other problems.
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.
How do you do an algebra equation with two variables?
The answer depends on what exactly you mean by doing an equation!
How do you solve algebra problems?
That depends on what information you know, and what information you need to find. The answer to your question usually takes one or two school semesters to learn and understand.
How do you solve a proportion if two variables are missing?
Calculus.

How do you solve x-y equals 13?
You need two independent linear equations to solve for two unknown variables.
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).
How do you solve 3ysquared equals x?
It is generally not possible to solve a single equation in two variables: this is one such.
How do you solve 7x equals 9y?
You cannot solve one linear equation with two unknown variables.
