Answer 1

Respuesta:

a: 0,4

b:5

c:11

d:10

e:4

f:2

g:3

Explicacion:

a:

$5x - 5 = 2x + 6 \\ 5x - 2x = 6 + 5 \\ 3x = 7 \\ x = \frac{7}{3 } \\ x = 2$

b:

$4x - 3 = 3x + 2 \\ 4 x - 3x = 2 + 3 \\ x = 5$

c:

$6x - 6 = 5x + 5 \\ 6x - 5x = 5 + 6 \\ x = 11$

d:

$5x + 10 = 2x + 40 \\ 5x - 2x = 40 - 10 \\ 3x = 30 \\ x = \frac{30}{3} \\ x = 10$

e:

$7x - 5 = 4x + 7 \\ 7x - 4x = 7 + 5 \\ 3x = 12 \\ x = \frac{12}{3} \\ x = 4$

f:

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

g:

$5x + 14 = 2x + 3 + 5 + - 3 \\ 5x - 2x = 3 + 5 - 3 - 14 \\ 3x = 8 - 3 - 14 \\ 3x = 5 - 14 \\ 3x = 9 \\ x = \frac{9}{3} \\ x = 3$
