Question

ajudaaa!!(marco como melhor)
a) 3x=x +8
b) 2x=8
c) x=4
d)x/x+500+100=x +250+500

Answer 1

Resposta:

Explicação passo a passo:

a)

3x = x + 8

3x - x = 8

2x = 8

x = 8/2

x = 4

b)

2x = 8

x = 8/2

x = 4

c)

x = 4

d)

$\frac{x}{x}+500+100=x+250+250\\\\\frac{x}{x}+600=x+500\\\\\frac{x}{x}-x=500-600\\\\\frac{x}{x}=x-100\\\\1=x-100\\x-100=1\\x=101$

Answer 2

Resposta:

Oi!

A) 3x=x+8

3x-x=8

2x=8

x=8/2

x=4

B) 2x=8

x=8/2

x=4

C) x/x+500+100=x+250+250

1/1+500+100=x+250+250

1+600=x+500

601=x+500

601-500=x

x=101
