Answer 1

Espero y te sirva, corona por favooor :))

-3. (-1+3)-8÷4-3. (-8+5)=

−3×2− 8/4 −3(−8+5)

−3×2− 8/4−3×−3

-6− 8/4−3×−3

−6−2−3×−3

−6−2−(−9)

−6−2+9

−8+9

4. (5-2)+8. (-1-2)+9=

4×3+8×(−1−2)+9

4×3+8×−3+9

12+8×−3+9

12−24+9

−12+9

-3

7-4. (-1-2)+4. (-8-2)+2÷2=

7−4×−3+4(−8−2)+2/2

7−4×−3+4×−10+2/2

7−(−12)+4×−10+2/2

7−(−12)−40+2/2

7−(−12)−40+1

7+12−40+1

19−40+1

−21+1

-20

-7+4. (6-7)+4÷(-9+4)=

−7+4×−1+4/-9+4

−7+4×−1+4/-5

−7−4+4/-5

−7−4−4/5

-59/5

8. (-9+4)-6+6. (-1-2)=

8×−5−6+6×(−1−2)

8×−5−6+6×−3

−40−6+6×−3

−40−6−18

−46−18

-64
