Penjelasan dengan langkah-langkah:

1. 5y = 4y + 10

5y – 4y = 10

y = 10

2.9p + 9 = 7p + 5

9p – 7p = 5 – 9

2p = – 4

p = – 4/2

p = – 2

3. 6p – 7 = 3p + 14

6p – 3p = 14 + 7

3p = 21

p = 21/3

p = 7

4. 4p + 6 = 24 – 2p

4p + 2p = 24 – 6

6p = 18

p = 18/6

p = 3

5. 2(x + 3) = 4

2x + 6 = 4

2x = 4 – 6

2x = – 2

x = – 1
