Answer 1

Olá, bom dia.

A)

$5x - 5 + x = 9 + x \\ 5x + x - x = 9 + 5 \\ 5x = 14 \\ x = \frac{14}{5} \\ x = 2.8$

B)

$7x - 4 - x = - 2x + 8 - 3x \\ 7x - x + 2x + 3x = 8 + 4 \\ 10x = 12 \\ x = \frac{12}{10} \\ x = 1.2$

C)

$- x - 5 + 4x = - 7x + 6x + 15 \\ - x + 4x + 7x - 6x = 15 + 5 \\ 4x = 20 \\ x = \frac{20}{4} \\ x = 5$

D)

$3x - 2x = 3x + 2 \\ 3x - 2x - 3x = 2 \\ - 2x = 2 \\ x = \frac{ - 2}{2} \\ x = - 1$

E)

$2 - 4x = 32 - 18x + 12 \\ - 4x + 18x = 12 + 32 - 2 \\ 14x = 42 \\ x = \frac{42}{14} \\ x = 3$

F)

$2x - 1 = - 3 + x + 4 \\ 2x - x = - 3 + 4 + 1 \\ x = 2$

G)

$3x - 2 - 2x - 3 = 0 \\ 3x - 2x = 2 + 3 \\ x = 5$

H)

$10 - 9x + 2x = 2 - 3x \\ - 9x + 2x + 3x = 2 - 10 \\ - 4x = - 8 \\ x = \frac{ - 4}{ - 8} \\ x = 0.5$

I)

$4x - 4 - 5x = - 6 + 90 \\ 4x - 5x = - 6 + 90 - 4 \\ - x = 80( - 1) \\ x = - 80$

J)

$2 - 3x = - 2x + 12 - 3x \\ - 3x + 2x + 3x = 12 - 2 \\ 2x = 10 \\ x = \frac{10}{2} \\ x = 5$

Foi bem cansativo... espero ter ajudado
