Answer 1

• 3u +8 =32

3u + 8 = 32

3u = 32 - 8

3u = 24

u = 24÷ 3

u = 8

comprobación

3(8) + 8 = 32

24 + 8 = 32

32 = 32

• 2u + 7 = 13

2u + 7 = 13

2u = 13 - 7

2u = 6

u = 6 ÷ 2

u = 3

comprobación

2(3) + 7 = 13

6 + 7 = 13

13 = 13

• 3y + 6 = 9

3y + 6 = 9

3y = 9 - 6

3y = 3

y = 3 ÷ 3

y = 1

comprobación

3(1) + 6 = 9

3 + 6 = 9

9 = 9

• 2x + 2 = 16

2x + 2 = 16

2x = 16- 2

2x = 14

x = 14 ÷ 2

x = 7

comprobación

2(7) + 2 = 16

14 + 2 = 16

16 = 16
