Question

me ajudem plssss é muuuiito urgente pfvvvv!!!!
Determine a raiz de cada equação:

a) X - 17 = - 9

b) 2x = - 7

c) 3x + 2 = 2x - 11

d) 2x = 16

e) 4t + 9 = 3t + 5

f) 10x - 8 - 2 = 7x - 4

g) 18x - 43 = 65

h) 2x + 6 = x + 18

i) 5x – 3 = 2x + 9

j) 3x – 5 = 13​

✔OLÁ!!!

$a)x - 17 = - 9 \\ x = - 9 + 17 \\ x = 8$

$b)2x = - 7 \\ x = - \frac{7}{2} \\ x = - 3.5$

$c)3x + 2 = 2x - 11 \\ 3x - 2x = - 11 - 2 \\ x = - 13$

$d)2x = 16 \\ x = \frac{16}{2} \\ x = 8$

$e)4t + 9 = 3t + 5 \\ 4t - 3t = 5 - 9 \\ t = - 4$

$f)10x - 8 - 2 = 7x - 4 \\ 10x - 10 = 7x - 4 \\ 10x - 7x = - 4 + 10 \\ 3x = 6 \\ x = \frac{6}{3} \\ x = 2$

$g)18x - 43 = 65 \\ 18x = 65 + 43 \\ 18x = 108 \\ x = \frac{108}{18} \\ x = 6$

$h)2x + 6 = x + 18 \\ 2x - x = 18 - 6 \\ x = 12$

$i)5x - 3 = 2x + 9 \\ 5x - 2x = 9 + 3 \\ 3x = 12 \\ x = \frac{12}{3} \\ x = 4$

$j)3x - 5 = 13 \\ 3x = 13 + 5 \\ 3x = 18 \\ x = \frac{18}{3} \\ x = 6$
