Question

2x/7-1/2=x; b)7-x/2-2x/3​

Answer 1

2x/7-1/2=x

2x/7-1=2x

2x/7=2x+1

2x=14x+7

-7=12x

x=-12/7

7-x/2-2x/3=0

7-x/2-2x=0

7-x/2=2x

7-x=4x

7=5x

x=7/5

Answer 2

Răspuns:

$\frac{2 \times }{7} - \frac{1}{2} = x \\ 4x - 7 = 14x \\ 4x - 14x = 7 \\ - 10x = 7 \\ x = - \frac{7}{10} \\ x = - 0.7 \\ b) \\ 7 - \frac{x}{2} - \frac{2x}{3} = \\ 7 - \frac{7}{6} x$
