Question

Resolva as equações
A)2×-5=3
B)3×+4=×+10
C)6×+2-18+6×=20

Answer 1

Resposta:

Explicação passo-a-passo:

A) x = (3 + 5 ) / 2 --- x = 4

B) 3x - x = 10 - 4 --- 2x = 6 --- x = 6/2 --- x = 3

C) 6x + 6x + 2 - 18 = 20 --- 12x -16 = 20 --- x = (20+16)/12 --- x = 3

Answer 2

Resposta:

A) 2x-5=3

2x=3+5

2x=8

x=8/2

x=4

B) 3x+4=x+10

3x-x=10-4

2x=6

x=6/2

x=3

C) 6x+2-18+6x=20

6x-16+6x=20

6x+6x=20+16

12x=36

x=36/12

x=3
