Question

7x - 4 - x = - 2x + 8 - 3x

Answer 1

7x-4-x=-2x+8-3x

7x -x +2x +3x= 8 + 4

7x +2x +3x -x = 8 + 4

12x -x = 12

11x= 12

x= 12/11

S= 12/11

Answer 2

$7x - 4 - x = - 2x + 8 - 3x \\ 6x - 4 = - 5x + 8 \\ 6x + 5x = 8 + 4 \\ 11x = 12 \\ \\ x = \frac{12}{11} \\ \\ x = 1.09091.....$

S= { 12 / 11 }

ou

S = {1,09091....}
