Álgebra

Algebra is the branch of mathematics that studies the equations, mathematical operations, polynomials and structures algébricas.Hoje will see the equations of first degree ie in which only contains one unknown
To solve we use the inverse operation, then we should apply the amount that the unknown side (x, y, z) to be the number of the denominator and the numerator the result of the inverse of the fraction
and then divide and find the value of x
example:

1-3x-2 = 16
    3x = 16 +2
    3x = 18
    x = 3/18
    x = 6



2 - 12-3x 30 =
      3x = 30 +12
      3x = 42
      x = 42/3
      x = 14


3 - 3x +12 = 30
     3x = 30-12
     3x = 18
     x = 3/18
     x = 6


              We may also use other results not only be 3x, we can use 2x, 4x, 5x, etc ...
