Question

solve for x ......on notebook​

Answer 1

Answer:

$5x + (x - \frac{1 - x}{2} ) - (7x - 1) + \frac{1}{2} = 0 \\ = 5x + \frac{x - 1}{2} - 7x + 1 + \frac{1}{2} = 0 \\ \frac{11x - 1}{2} - \frac{14x + 3}{2} = 0 \\ = 11x - 14x - 1 - 3 = 0 \\ = - 3x - 4 = 0 \\ = - 3x = 4 \\ = x = \frac{ - 4}{3}$
