40 + 24 - 3 + 9 + 10 x = 100

3 x + x + 12 + 4 - 2 = 10​

Answer 1

Explicação passo-a-passo:

40 + 24 - 3 + 9 + 10 x = 100

24-3+9+10x=100-40

24-3+9+10x=60

-3+9+10x=60-24

-3+9+10x=36

9+10x=36+3

9+10x=39

10x=39-9

10x=30

10x/10=30/10

x=10

3 x + x + 12 + 4 - 2 = 10

4x+12+4-2=10

4x+4-2=10-12

4x+4-2= -2

4x-2= -2-2

4x-2= -4

4x= -4+2

4x= -2

4x/4= -2/4

x= -2

Answer 2

Resposta: 2 e -2

Explicação passo-a-passo:

40 + 24 - 3 + 9 + 10 x = 100

10x = 100 - 83 + 3

10x = 20

x = 20/10

x = 2

3 x + x + 12 + 4 - 2 = 10​

4x = 10 - 16 + 2

4x = -4

x = -4/4

x = -2
