Question

Calcule o valor de x:
A) 3 + x = 0

B) 23x + 2 = 2

C)5x – 3x = 30

2) 4x + 10 = 45 – 3x

Answer 1

Resposta:

A) X = - 3

B) X = 0

C) 15

2) x =5

Explicação passo-a-passo:

A) X =0-3 = - 3

B) 23x = 2-2

X =0/23

X=0

C) 5x - 3x =30

2x =30

X =30 /2

X =15

2) 4x +3x = 45 - 10

7x = 35

X = 5
