A ) -------- + 690 = 800


B ) 4.750 + -------- = 6.000


C ) -------- - 420 = 1.600


D ) -------- - 1.250 = 3.600 ​

Answer 1

a) x + 690 = 800

x = 800-690

x = 110

b)  4.750 + x = 6.000

x = 6000 - 4750

x = 1250

c) x - 420 = 1.600

x = 1600 - 420

x = 1180

d) x - 1.250 = 3.600

x = 3600 - 1250

x = 2350
