Penjelasan dengan langkah-langkah:

2. 2a = 14

a = 14/2

a = 7

3. x/4 = -1

x = -1 × 4

x = -4

4. -¾x = -⅜

x = -⅜ ÷ (‐¾)

x = -⅜ × (-⁴/3)

x = 12/24

x = ½

5. 8x - 8 = -28

8x = -28 + 8

8x = -20

x = -20/8

x = -2⁴/8

= -2½

6. 4y + 5 = 37

4y = 37 - 5

4y = 32

y = 32/4

y = 8

7. 7y - 4 = 5y

7y - 5y = 4

2y = 4

y = 4/2

y = 2

8. 4p + 6 = 24 - 2p

4p + 2p = 24 - 6

6p = 18

p = 18/6

p = 3

9. 5p - 8 = 7p + 12

5p - 7p = 12 + 8

-2p = 20

p = 20/-2

p = -10

10. 3(x+2) = 2(3x-4)

3x + 6 = 6x - 8

3x - 6x = -8 - 6

-3x = -14

x = -14/-3

x = 4⅔
