g) A+3= 10
h) X-3= -1​

Answer 1

Resposta:

Explicação passo-a-passo:

a) x - 2 = 10

x = 10 + 2

x = 12

b) x - 5 = 15

x = 15 + 5

x = 20

c) x - 3 = 2

x = 2 + 3

x = 5

d) x + 4 = 8

x = 8 - 4

x = 4

e) x + 3 = 1

x = 1 - 3

x = -2

f) y + 8 = 10

y = 10 - 8

y = 2

g) a + 3 = 10

a = 10 - 3

a = 7

h) x - 3 = - 1

x = - 1 + (-3)

x = -4
