Question

calcular el valor de

1) – 9m – 12 = 15

2) x
6 –7=–10

3) x-5=x+x
2 9 3

4) 16x – 10 – 4x = 12x – 30 – 5x

5) 8x – 6 + x – 3 = –5x + 12 – x

6) –3 + 3x + 10 – 5x = x + 12 – 4x + 15

7) 2 + 3(x – 4) = –(x + 6)

8) Calcula “n – m”
5(m – 3)= 10; n –8 = –6
7

9) 2x – 3 = 7 +5x
3

10) 5(x – 4) – 3(x – 2) = 7x + (–6x + 5)

Answer 1

Respuesta:

1) -9m-12=15

-9m =15+12

-9m =27÷-9

m= -3

2) ×6-7=-10

×-1=-10+1

×=-10÷1

×=-10

3) Nose

4) 16×-10-4×=12×-30-5×

12×-10=12×-30-5×

12x-10=7×-30

12×-7×-10=7×-30

12×-7×-10=-30

12×-7×=-30+10

5×=-30+10

5×=-20

x=-20÷5

x=-4

5) 8×-6+×-3=-5×+12-×

9x-6-3=-5×+12-×

9×-9=-5×+12-×

9×-9=-6×+12

9×+6×-9=12

9×+6×=12+9

15×=12+9

15x=21÷15

x=7

5

6) -3+3×+10-5×=×+12-4×+15

7+3×-5×=×+12-4×+15

7-2×=×+12-4×+15

7-2×=-3×+12+15

7-2×=-3×+27

7-2×+3×=27

-2×+3×=27-7

x=27-7

x=20

7)2+3(×-4)=-(×+6)

2+3×-12=-×+6

-10+3×=-×+6

-10+3×+×=-6

3×+×=-6+10

4×=-6+10

4×=4

×=4÷4

x=1

8)Nose

9) 2×-3=7+5×3

2×-3=7+15

2×-3=22

2×=22+3

2×=25

x=25÷2

x=25
