Jawaban:

a) 14x – 10 + 4x = 17x – 7

14x + 4x – 17x = –7 + 10

18x – 17x = 3

x = 3

b) 3(2x + 7) = 5(x – 4)

6x + 21 = 5x – 20

6x – 5x = –20 – 21

x = –41

c) 2(5x – 6) = 3(3x – 7) +2x

10x – 12 = 9x – 21 + 2x

10x = 11x – 21 + 12

10x – 11x = –9

–x = –9

x = 9

d) 5(y – 4) + 2y = 6(y – 3)

5y – 20 + 2y = 6y – 18

7y – 6y = –18 + 20

y = 2

e) 8y – 15 = 9y

8y – 9y = 15

–y = 15

y = –15

Selebihnya, kamu coba lanjutkan ya.. semangat ^_^
