Sua Pergunta

1) Resolva as equações:

a) 2x + 23 = 43

$2x = 43 - 23 \\ 2x = 20 \\ x = \frac{20}{2} \\ x = 10$

b) x – 10 = 35

$x = 35 + 10 \\ x = 45$

c) 2x + 32 = 14

$2x = 14 - 32 \\ 2x = - 18 \\ x = \frac{ - 18}{2} \\ x = - 9$

d) 3x – 11 = 7

$3x = 7 + 11 \\ 3x = 18 \\ x = \frac{18}{3} \\ x = 6$

e) x + 24 = – 9

$x = - 9 - 24 \\ x = - 33$

f) – 4x = – 36

$x = \frac{ - 36}{ - 4} \\ x = - 9$

g) 5x + 9 = – 31

$5x = - 31 - 9 \\ 5x = - 40 \\ x = \frac{ - 40}{5} \\ x = - 8$

h) – 3x – 8 = 37

$- 3x = 37 + 8 \\ - 3x = 45 \\ x = \frac{45}{ - 3} \\ x = 15$

i) 6x + 20 = – 16

$6x = - 16 - 20 \\ 6x = - 36 \\ x = \frac{ - 36}{6} \\ x = - 36$

j) – 5x + 12 = 17

$- 5x = 17 - 12 \\ - 5x = 5 \\ x = \frac{5}{ - 5} \\ x = - 5$

espero ter ajudado!!!
