Question

9=×+(-12)
-3y = 24
1/2 × = 8
3-9=4+×- 7+6
​

Answer 1

Respuesta:

1: x = 11

2: y = -8

x = 16

4: x = - 9

Explicación paso a paso:

1:

9 = x-2

-x = -2-9

-x=-11

x = 11

2:

-3y / (-3) = 24 / (-3)

y = 24 / (-3)

y = -8

3:

ambos se multiplican por 2

2 * 1/2 x = 2 * 8

x = 2*8

x = 16

4:

- 6 = 3 + x

- x - 6 = 3

- x = 9

x = -9
