4) ×-9=3
3


5)3×-5=+13


6)8×+3=×-37


7)-4×-1×+29


8)-9×+10=3×-2
​

Answer 1

Resposta:

1) x= - 72/ 9 x= - 8

2) 3x= - 43 +4 3x = - 39 x = - 39/3 ×= - 13

3) x/2=5 X = 5x2 X= 10

4) X/3-9=3 X/3= 3+9 X/3= 12 X= 12x3 X= 36

5) 3x= 13 +5 3x= 18 3x= 18/3 x= 6

6) 8x -x = -37 - 3 7x= - 40 x= -40/ 7 x =5.7

7) - 5x = -29 (× -1) 5x= 29 x= 29/5 x = 5.8

8) -9x -3x= - 2 -10 - 12x= - 12 (×-1) x = 12/12 x = 1
