Question

a) -4(x+5)-2x-10
b) 3+5(x-4)-3x-12
c) 1-3(x-1)÷2=-½(x-⅔)​

Answer 1

Resposta:

a)-6(x+5)

b)5x-32

c)x=15/11

Explicação passo-a-passo:

fatorizada :a)-4(x+5)-2x-10

-4-20-2x-10

-6-20-10

-6x-30

sem fatorizada:a)-4(x+5)-2x-10

-4(x+5)-2 (x+5)

-6(x+5)

b)3+5(x-4)-3x-12

5(x-4)-12

5x-20-12

5x-32

c) 1-3(x-1)÷2=-½(x-⅔)

1-3(x-1)/2=-1/2×(-2/3)

1-3x-3/2=1/3x

6-3(3x-3)=2x

6-9x+9=2x

15-9x=2x

-9x-2x=-15

-11x=-15

x=15/11
