Answer 1

6. 10/x=6/9
x=10×9/6=15
x=10-15=5

8. 10/x=5/7
x=10×7/5=14
x=14-10=4

LKS kita samaan yak???!!!

Answer 2

6) Jawab
10/6 = (10+y)/9
10 x 9 = (10+y) x 6
90 = (10+y) x 6
90/6 = 10 + y
15 = 10 + y
y = 15 - 10
y = 5

7) Jawab
6/5 = y/9
6 x 9 = 5y
54 = 5y
y = 54/5
y = 10,8

8) Jawab
10/5 = (10+y)/7
10 x 7 = 5(10+y)
70 = 5(10+y)
70/5 = 10 +y
14 = 10 + y
y = 14 - 10
y = 4

9) Jawab
4/10 = y/20
4 x 20 = 10y
80 = 10y
y = 80/10
y = 8
