g) 128 + x = 900 ________________________________________________

Answer 1

Vamos là.

a) x + 1 = 9, x = 8

b) x - 2 = 8, x = 10

c) x - 8 = -10, x = -2

d) x + 101 = 300, x = 300 - 101 = 199

e) x - 279 = 237, x = 237 + 279 = 516

f) 17 + x = 13, x = 13 - 17 = -4

g) 128 + x = 900, x = 900 - 128 = 772
