Answer 1

Respuesta:

9- 12 12-6

Explicación paso a paso:

9-

×+3÷2 + 11 =20

×÷2 = 20-11 -3

× = 6 ×2

×= 12

12- 2x+1÷3 -4 =1

2×÷3 =1+4-1

2x = 4×3

x= 12÷2

× = 6

Answer 2

Explicación paso a paso:

6. (3x+4)/4 = 7

3x+4 = 7×4

3x+4 =28

3x= 24

x= 24/3

x=8

9. (x+3)/2 +11 =20

(x+3)/2 = 20 - 11

(x+3)/2 = 9

(x+3)=9×2

x+3 = 18

x=15

12. (2x+1)/3 - 4 = 1

(2x+1)/3 = 5

2x +1 = 5×3

2x +1= 15

2x =14

x=7

15. (9x+7)/5=1+2^2

(9x+7)/5 =1+4

( 9x+7)/5 = 5

9x+7 =5×5

9x+7=25

9x=18

x=2
