Question

1) x - 2,76 = -4
2) x - 8 1/4 = -3,2
3) y - 2 7/9 = -8

Answer 1

1) х - 2,76 = - 4

х = - 4 + 2,76

х = - ( 4 - 2,76 )

х = - 1,24

2)

$x - 8 \frac{1}{4} = - 3.2$

$x - 8.25 = - 3.2$

$x = - 3.2 + 8.25$

$x = - (8.25 - 3.2)$

$x = - 5.05$

3)

$y - 2 \frac{7}{9} = - 8$

$y = - 8 + 2 \frac{7}{9}$

$y = - \frac{72}{9} + \frac{25}{9}$

$y = - ( \frac{72}{9} - \frac{25}{9})$

$y = - \frac{42}{9}$

$y = - \frac{14}{3}$
