Question

encontrar el valor de la incognita:
3x = 9
-5y = -30
x/2 = 7
4 (x + 1) + 2(x - 3) = 4
5 (z - 3) + (z + 2) = -1
1/2 m + 4/3 m = 22
5/2 x - 7/6x = 4/3


las que estan con diagonal son fracciones

Answer 1

Respuesta:

si es factorizar la expresion es 7(x-1)

si es simplificar la expresion es 7 x-7

Answer 2

Respuesta:

Abajo XD

Explicación paso a paso:

3x = 9

x = 9/3

x = 3

-5y = - 30

30 = 5y

30/5 = y

6 = y

x/2 = 7

x = 7. 2

x = 14

4 (x + 1) + 2(x - 3) = 4

4x + 4 + 2x - 6 = 4

4x + 2x + 4 - 6 = 4

6x - 2 = 4

6x = 4 + 2

6x = 6

x = 6/6

x = 1

5 (z - 3) + (z + 2) = -1

5z - 15 + z + 2 = - 1

5z + z - 15 + 2 = - 1

6z - 13 = - 1

6z = 13 - 1

6z = 12

z = 12/6

z = 6

1/2 m + 4/3 m = 22

(1/2 + 4/3)m = 22

(3 + 8/6)m = 22

11/6 m = 22

m = 22 x 6/11

m = 132/11

m = 12

5/2 x - 7/6x = 4/3

(5/2 - 7/6)x = 4/3

(30 - 14/12)x = 4/3

(16/12)x = 4/3

x = 4. 12/3. 16

x = 48/48

x = 1
