For example:1 = 1
1 = 0
x = 5
x = x + 1
y = x + 5
So basically, any two expressions (numbers, or something that can be calculated to give a number), with an equal sign in between.

The multiplicative inverse, or reciprocal, of a number "x", is "1/x". For example, the multiplicative inverse of 5 is 1/5. For a fraction, just exchange numerator and denominator. For example, the multiplicative inverse of 2/5 is 5/2.
Produce an example of a system ofequations.
Linear equations have a variable only to the first degree(something to the power of 1). For example: 2x + 1 = 5 , 4y - 95 = 3y are linear equations. Non-linear equation have a variable that has a second degree or greater. For example: x2 + 3 = 19, 3x3 - 10 = 14 are non-linear equations.
This means that, for example: 15 - 5 = 15 + (-5) 15 - (-5) = 15 + 5 Knowing this relationship can both help you do the actual calculations, and assist you in solving equations.

Just write any equation that involves with the number five, for example: 5 + 1 = 6, 2 x 5 + 1 = 11, 52 = 25, etc., then replace the "5" in the equation with an "x".

An example is x+y=3 and 2y+x=5 these are more or less known as simultaenous equations
It is essentially a list of equations that have common unknown variables in all of them. For example, a+b-c=3 4a+b+c=1 a-2b-7c=-2 would be a system of equations. If there are the same number of equations and variables you can usually, but not always, find the solutions. Since there are 3 equations and 3 variables (a, b, and c) in this example one can usually find the value of those three variables.
For example, x = x + 1.
Two linear equations that are parallel with have the sameslope, or the m value in y = mx + b will be the same.For example, y = 3x + 5 is parallel to y = 3x - 6
Times itself. For example, 4 squared would be 4x4 = 16. 5 squared would be 5x5 = 25 etc
Any equation which does not require you to divide by four, or its equivalent. For example 1600 divided by 5. There is an infinity of such equations.
