Question

Observe os exemplos e resolva as equacoes

ex 5x = 30 -6x = -12
x= 30/5 x = -12/-6
x = 6 x = 2


a) 2x = -8
b)3y = 18
c) 2x = 0
d) -3x = 6
e) 2x + 4 = 6
f) 4x = -16
g) -2y = 0
h) 3y +1 = `0

PRECISO DOS CALCULOS

Answer 1

a) 2x= -8
x= -8-2
x=-10


b) 3y= 18
y= 18-3
y= 15


c) 2x= 0
x= 0-2
x= -2


d) -3x= 6
x= 6+3
x= 9


e) 2x+4= 6
2x= 6-4
2x= 2
x= 2/2
x= 1


f) 4x= -16
x= -16/-4
x= 4


g) -2y= 0
y= 0/2


h) 3y+1= 0
3y= 0-1
y= -1/-3
