Question

x +15=-9
n + (-16)=13
y - ( -12)=4
x - 31 =-20
z- (-6),= -10
ecuaciones porfa ayuda

Answer 1

$x + 15 = - 9 \\ x = - 9 - 15 \\ x = - 24$

$n + ( - 16) = 13 \\ n - 16 = 13 \\ n = 13 + 16 \\ n = 29$

$y - ( - 12) = 4 \\ y + 12 = 4 \\ y = 4 - 12 \\ y = - 8$

$x - 31 - 20 \\ x = - 20 + 31 \\ x = 11$

$z - ( - 6) = - 10 \\ z + 6 = - 10 \\ z = - 10 - 6 \\ z = - 16$
