7X + 2 = 5X - 1
subtract 5X from both sides
2X + 2 = -1
==============
If an equation has two variables, we'll call them (x,y), the variables can be any value as long as both sides of the equation have the same result. If the equation was x = y, then the variables could be (1,1), (2,2), (3,3),etc...
A calculator can be used to proportions to answer a equation. This is easier to solve when having variables on both sides.
combining like terms or subtracting from both sides of the equation.
The variables may have different values.
You first have to get rid of the numbers that don't have variables. then you divide by the variable and solve for it.
First, get the radical by itself. Then, square both sides of the equation. Then just solve the rest.
it means the lataduide line
The addition of the opposite, to both sides of the equation. keep it equal
The answer in an equation is called the "solution." It is the value or values that satisfy the equation, making both sides equal when substituted into the expression. In the case of equations with multiple variables, the solution may represent a set of values.
I'm pretty sure you mean balancing an equation to solve for a particular vairable
You try to bring all instances of the variable to one side. Here is an example:5x + 5 = 3x - 2 Subtracting 3x on both sides: 2x + 5 = -2 Subtracting 5 on both sides: 2x = -7
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".
