Answer 1

Resposta:

X-1=5

X = 1 + 5  

X = 6

____________

2x+4=16  

2X = 16 – 4

2X = 12

X = 12/2

X= 6

____________

3x=15

X = 15/3

X = 5

____________

2x=10

X = 10/2

X = 5

____________

3x=-9

X = -9/3

X = -3

____________

2x=2=12-5x  

____________

3x-13=8

3X = 8 + 13

3X = 21

X = 21/3

X = 7

____________

4x-9=23

4X = 23 + 9
