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.
one example of a mathematical equation could be (+2x-5)-(-2x+5+10a) and the answer would be (-5a3+4x-2)
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.
The fact family for the numbers 2, 5, and 10 consists of the addition and subtraction equations that relate these numbers. The addition equations are 2 + 5 = 7 and 5 + 2 = 7, while the subtraction equations are 10 - 5 = 5 and 10 - 2 = 2. The relationships highlight how these numbers can be combined or separated to form different equations.
Equivalent equations are two or more equations that have the same solution set. For example, the equations (2x + 3 = 7) and (4x + 6 = 14) are equivalent because they both simplify to (x = 2). This means that any value of (x) that satisfies one equation will also satisfy the other.
Times itself. For example, 4 squared would be 4x4 = 16. 5 squared would be 5x5 = 25 etc
