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.
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.
