How do you figure out equations with the variable on both sides?

You are probably referring to a linear equation. In this case get the variables all on one side. example: 5n + 5 = 3n -2 2n + 5 = -2 2n = -7 n = -7/2 or - 3.5

To solve one-step equations find out what operation was done to the variable then do the operation to both sides of the equation?
Reverse Thank God for Apex... Im graduating :)
Which is the best way to solve the equation?
That depends on the equation. In general, you'll try to isolate the variable, by using operations (on both sides of the equation) that get rid of anything other than the variable, on the side the variable is on.
For systems in which there is no linear equation you can isolate and substitute a variable that is what in both equations?
squared
What is a method for solving a system of linear equations in which you multiply one or both equations by a number to get rid of a variable term?
It is called solving by elimination.
If you are asked to solve a system of equations in which there is no linear equation to start with you can sometimes begin isolating and substituting a variable that is squared in both equations?
true
Can you subtract the same number from both sides of an equation?
Yes, it is required to figure out some equations.

How do you solve this equations 4x plus 5 equals 13?
4x + 5 = 13. To solve algebraic equations, you need to get the variable by itself on one side of the equation. Start by subtracting 5 from both sides >>> 4x = 8. Then divide both sides by 4 to find what 'x' equals >>> x = 2.

How can we solve linear equations in one variable?
First combine all like terms so that the equation is in the form ax + b = 0 Subtract b from both sides to give ax = -b Divide both sides by a which gives x = -b/a.
For systems in which there is no linear equation you can isolate and substitute a variable that is what in both equations?
squared
How can you use addition to find the variable in subtracting equations?
x-3=0 so add 3 to both sides to isolate the variable. x-3=0 +3 | +3 ________ x-3+3=o+3 _________ x=3
Why do you use x in math problems?
x represents an unknown variable, usually to be solved in algebraic equations eg) 2x = 10 divide both sides of the equation by 2 to get x = 5

How do you do b equals 2.4 in two step equations?
To do b equals 2.4 in two step equations, we need to first isolate the variable b on one side of the equation. To do this, we can undo any operations that have been applied to b. For example, if we had the equation 4b = 9.6, we can divide both sides by 4 to get b = 2.4. Similarly, if we had the equation 4b - 8 = 9.6, we can add 8 to both sides of the equation, then divide both sides by 4 to get b = 2.4. Once we have isolated the variable b on one side of the equation, we can set it equal to 2.4 to solve the equation.
