Answer 1

1) 5X + 5 = 60

5X = 60 - 5

5X = 55

X = 55/5

X = 11

Resposta - B) 11

2) 10X = 6X + 28

10X - 6X = 28

4X = 28

X = 28/4

X = 7

Resposta - C) 7

3) X + 1 = 9

X = 9 - 1

X = 8

Resposta - A) V = {8}

4) 6X = 2X + 28

6X - 2X = 28

4X = 28

X = 28/4

X = 7

Resposta - C) 7

5) 4 . ( X + 1 ) = 12

4X + 4 = 12

4X = 12 - 4

4X = 8

X = 8/4

X = 2

Resposta - C) 2
