Answer 1

Resposta:

i) 4 = x - 10 | x = 10 + 4 | x = 14

J) 7 = x + 8 | x = 7 - 8 | x = -1

K) x - 1 = 5 | x = 5 + 1 | x = 6

L) 2 x + 4 =16 | 2x = 16 - 4 | 2x = 12 | x=12/2 | x=6

M) 3 x = 15 | x = 15/3 | x = 5

N) 2 x = 10 | x = 10/2 | x = 5

O) 3 x = -9 | x = -9/3 | x = -3

P) 2 x -2 = 12- 5 x | 2x + 5x - 2 = 12 | 7x = 12 + 2 | 7x = 14 | x = 14/7 | x = 2

Q) 3 x - 13 = 8 | 3x = 8 + 13 | 3x = 21 | x = 21/3 | x = 7

R) 4 x - 9 = 23 | 4x = 23 + 9 | 4x = 32 | x = 32/4 | x = 8

S) 7 x - 33 = -12 | 7x = -12 + 33 | 7x = 21 | x = 21/7 | x = 3

T) 33 + x = 5-3 x | x + 3x = 5 - 33 | 4x = -28 | x = -28/4 | x = -7

Espero ter ajudado!
