Question

4x - (2x - 1) + x = 2x - (2 + x) - X

x + (x + 3)(x - 3) = 3 + x(x + 1)

7x - [(x + 5)-(3x - 1)] = 12​

Answer 1

Explicación paso a paso:

4x - (2x - 1) + x = 2x - (2 + x) - x

4x - 2x + 1 + x = 2x - 2 - x - x

4x - 2x+x -2x +x +x = -2-1

3x = -3

x = -3/3

x = -1

x + (x + 3)(x - 3) = 3 + x(x + 1)

x + x²-9 = 3 + x²+x

x + x² -  x²-x = 3 +9

0 = 12

No tiene solucion

7x - [(x + 5)-(3x - 1)] = 12​

7x - (x + 5-3x + 1] = 12​

7x - x - 5+3x - 1 = 12​

7x - x +3x  = 12​+5+1

9x = 18

x = 18/9

x =2
