Question

1- DESCOBRINDO O VALOR DE CADA NÚMERO:
a) y - 3 = -20
b) 5 . Z = -10
c) 5 + x = -5
d) 8 - Z= - 10

Answer 1

a)
Y - 3 = -20
Y = -20 + 3
Y= -17

b)
5.Z = -10
Z= -10÷5
Z= -2

c)
5 + X = -5
X = -5 - 5
X = -10

d)8 - Z = -10
-Z = -10 - 8
-Z = -18 .(-1)
Z = 18

Answer 2

Y-3= -20 Y= -20+3 Y= -17 5+X= -5 X= -5-5 X= -10 8-Z= -10 -Z= -10+8 -Z= -2(-2) Z=2
