2=2
1. Resuelve las siguientes ecuaciones y su comprobación
X + 8 = 13
a-3 = 6
f+9 = 15
h-3 = 9
x + 7 = 10
y-1 =11
m + 12 = 14
n-5 = 8
b + 2 = 7
d - 15 = 30
t + 9 = 22
w - 19 = 31​

Answer 1

Respuesta:

$x + 8 = 13 \\ x = 13 - 8 \\ x = 5 \\ \\ 5 + 8 = 13 \\ 13 = 13$

$a - 3 = 6 \\ a = 6 + 3 \\ a = 9 \\ \\ 9 - 3 = 6 \\ 6 = 6$

$f + 9 = 15 \\ f = 15 - 9 \\ f = 6 \\ \\ 6 + 9 = 15 \\ 15 = 15$

$h - 3 = 9 \\ h = 9 + 3 \\ h = 12 \\ \\ 12 - 3 = 9 \\ 9 = 9$

$x + 7 = 10 \\ x = 10 - 7 \\ x = 3 \\ \\ 3 + 7 = 10 \\ 10 = 10$

$y - 1 = 11 \\ y = 11 + 1 \\ y = 12 \\ \\ 12 - 1 = 11 \\ 11 = 11$

$m + 12 = 14 \\ m = 14 - 12 \\ m = 2 \\ \\ 2 + 12 = 14 \\ 14 = 14$

$n - 5 = 8 \\ n = 8 + 5 \\ n = 13 \\ \\ 13 - 5 = 8 \\ 8 = 8$

$b + 2 = 7 \\ b = 7 - 2 \\ b = 5 \\ \\ 5 + 2 = 7 \\ 7 = 7$

$d - 15 = 30 \\ d = 30 + 15 \\ d = 45 \\ \\ 45 - 15 = 30 \\ 30 = 30$

$t + 9 = 22 \\ t = 22 - 9 \\ t = 13 \\ \\ 13 + 9 = 22 \\ 22 = 22$

$w - 19 = 31 \\ w = 31 + 19 \\ w = 50 \\ \\ 50 - 19 = 31 \\ 31 = 31$
