Answer 1

Respuesta:

$a)2z + 8 = 24 \\ 2z = 24 - 8 \\ 2z = 16 \\ z = 8$

$b)3a + 8 = 20 \\ 3a = 20 - 8 \\ 3a = 12 \\ a = 4$

$c)3a + 2 = 29 \\ 3a = 29 - 2 \\ 3a = 27 \\ a = 9$

$d) 2u + 3 = 3 \\ 2u = 3 - 3 \\ 2u = 0 \\ u = 0$

$e)2c + 2 = 22 \\ 2c = 22 - 2 \\ 2c = 20 \\ c = 10$

$f)2a + 7 = 17 \\ 2a = 17 - 7 \\ 2a = 10 \\ a = 5$

$g)2v + 9 = 15 \\ 2v = 15 - 9 \\ 2v = 6 \\ v = 3$

$h)3v + 10 = 40 \\ 3v = 40 - 10 \\ 3v = 30 \\ v = 10$

$i)2b + 9 = 11 \\ 2b = 11 - 9 \\ 2b = 2 \\ b = 1$

$j)2u + 9 = 21 \\ 2u = 21 - 9 \\ 2u = 12 \\ u = 6$

$k)3b + 8 = 17 \\ 3b = 17 - 8 \\ 3b = 9 \\ b = 3$

$l)3x + 10 = 16 \\ 3x = 16 - 10 \\ 3x = 6 \\ x = 2$

$m)2u + 8 = 18 \\ 2u = 18 - 8 \\ 2u = 10 \\ u = 5$

$n)3y + 9 = 18 \\ 3y = 18 -9 \\ 3y = 9 \\ y = 3$

$o)2a + 9 = 15 \\ 2a = 15 - 9 \\ 2a = 6 \\ a = 3$
