a).2x+3=11

2x = 11 – 3

2x = 8

x = 4

b).4a+2=18

4a = 18 – 2

4a = 16

a = 4

c).2p+5=20

2p = 20 – 5

2p = 15

p = 15/2

d).3y-4=25

3y = 25 + 4

3y = 29

y = 29/3

Jawaban:

a). 2x + 3 = 11

2x = 11 – 3

2x = 8

x = 8 ÷ 2

x = 4

b). 4a + 2 = 18

4a = 18 -2

4a = 16

a = 16 ÷ 4

a = 4

c). 2p + 5 = 20

2p = 20 – 5

2p = 15

p = 15 ÷ 2

p = 15/2 atau 7,5

d). 3y – 4 = 25

3y = 25 + 4

3y = 29

y = 29 ÷ 3

y = 29/3 atau 9,66
