Question

C) x+x-4=17-2x+1
D)x+2x+3-5x=4x-9
E)5x+6x-16=3x+2x-4
F)5x+4=3x-2x+4

Answer 1

Resposta: c) x=11/2

d) x=2

e) x=2

f) x=0

Explicação passo-a-passo:

c) x+x-4=17-2x+1=

2x-4=17-2x+1=

2x+2x=17+1+4

4x=22

x=22/4=11/2

d) x+2x+3-5x=4x-9=

x+2x-5x-4x=-9-3=

-6x=-12

x=-12/-6

x=2

e) 5x+6x-16=3x+2x-4

5x+6x-3x-2x=-4+16

6x=12

x=12/6

x=2

f) 5x+4=3x-2x+4

5x-3x+2x=4-4

4x=0

x=0/4

x=0

Espero ter ajudado! Bons estudos!

Answer 2

Resposta:

Explicação passo-a-passo:

C) x+x-4=17-2x+1

2x-4=18-2x

2x+2x=18+4

4x=22

x=22/4

x=11/2

D)x+2x+3-5x=4x-9

-2x+3=4x-9

-2x-4x=-9-3

-6x=-12

x=2

E)5x+6x-16=3x+2x-4

11x-16=5x-4

11x-5x=-4+16

6x=12

x=2

F)5x+4=3x-2x+4

5x+4=x+4

5x-x=4-4

4x=0

x=0
