Answer 1

Resposta:

b) X= 90

c) Y= 228

d) b= 710

Explicação passo-a-passo:

b)

x - 10 = 80

<=> X = 80 + 10

<=> X = 90

C)

y + 345 = 573

<=> y = 573 - 345

<=> y = 228

d)

b - 32 = 678

<=> b = 678 + 32

<=> b = 710

Answer 2

b) x-10=80

x=80+10

x=90

c) y+345=573

y=573-345

y=228

d) b-32=678

b=678+32

b=710
