Question

Preciso resolver essa equação: 5+4(x-1)=$\frac{18x-9}{3}$

Answer 1

5+4(x-1)=18x-9/3

3.[5+4(x-1)]= 18x-9
3[5+4x-4] = 18x-9
3[4x+1] = 18x - 9
12x + 3 = 18x -9
3+9 = 18x - 12x
12 = 6x
x = 12/6
x = 2

Answer 2

  5+4(x-1)=

     15 + 12(x-1) = 18x - 9
      15 + 12x - 12 = 18x - 9
           18x - 12x = 15 -12+9
                  6x = 12
                    x = 2
