Question

1) 2x - 2 = 12 - 5x
2)7y-10=y+50
3) 2x+4=16​

Answer 1

1) 2x - 2 = 12 - 5x

2x+5x = 12+2

7x = 14

x = 14/7

x = 2

2)7y-10=y+50

7y-y = 50+10

6y = 60

y = 60/6

y = 10

3) 2x+4=16

2x = 16-4

2x = 12

x = 12/2

x = 6

Answer 2

Resposta:

1) 2x - 2 = 12 - 5x

2x + 5x = 12 + 2

7x = 14

x = 14/7

x = 2

2) 7y - 10 = y + 50

7y - y = 50 + 10

6y = 60

y = 60/6

y = 10

3) 2x - 4 = 16

2x = 16 - 4

2x = 12

x = 12/2

x = 6
