Question

Resolva as equações
A) ×-9=0
B)2×-16=0
C)-3×)27=0
D)×+36=0
E)-4×+100=0

Answer 1

A) x = 9

B)x = 8

C)9 = x

D)x = -36

E)25 =x

Explicação:

A) x-9 = 0

x = 0+9

x = 9

B)2x-16 = 0

2x= 0+16

2x = 16

x = 16÷2

x = 8

C)-3x+27 = 0

27 = 0+3x

27-0 = 3x

27 = 3x

27÷3 = x

D)x+36 = 0

x = 0-36

x = -36

E)-4x+100 = 0

100 = 0+4x

100-0 = 4x

100 = 4x

100÷4 = x

25 = x
