Answer 1

Resposta:

a) 2x + 100g= 1000g

2x= 1000g-100g

2x= 900g

x= 900g/2

x= 450g

b) 700g = x + 250g

x + 250g = 700g

x= 700g - 250g

x= 450g

c) 4x + 250g= 1000g

4x = 1000g - 250g

4x= 750g

x= 750g/4

x= 187,5g

d) 1000g + 250g = 500g + 100g +2x

1250g = 600g + 2x

2x+600g= 1250g

2x= 1250g - 600g

2x= 650

x= 650g/2

x= 325g
