Solve the following equations for x. Show the step by step process.

1. 3x - 19 = 2
2. 4x + 12x = 6^2+ 4(11)
3. X/8 + 7 = - 10
4. 4(5x-9) = -2(3x +7)
5. 1/2 x - 5 = (-3/8) x +2
6. 3(x - 4) - (x-5) = 2x - 11

Respuesta :

1. 3x - 19 = 2
        +19    +19
           3x = 21
           ÷3   ÷3
          x= 7
2. 4x + 12x = 6² + 4(11)
            16x = 36 + 44
            16x = 80
           ÷16   ÷16
             x= 5
