Resolução

x - 2 = 10

x = 10 + 2

$\textsf{\red{\large x = 12}}$

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

x - 5 = 15

x = 15 + 5

$\textsf{\red{\large x = 20 }}$

x - 3 = 2

x = 2 + 3

$\textsf{\red{\large x = 5 }}$

x + 4 = 8

x = 8 - 4

$\textsf{\red{\large x = 4 }}$

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

x + 3 = 1

x = 1 - 3

$\textsf{\red{\large x = -2}}$
