Question

x, y and z are three numbers. x is 10 more than y and y is 8 more than z. The sum of the three numbers is 47. what is the value of x, y and z

Answer 1

Answer:

25

Step-by-step explanation:

x=y+10

y=z+8

x+y+z=47

y+10+y+z=47

2y+z=47 -10=37

2(z+8)+z=37

2z+16+z=37

3z=37-16=21

z=21/3=7

y=z+8=7+8=15

x=y+10=15+10=25

Answer 2

Answer:

25

Step-by-step explanation:

x=y+10

y=2+8

x+y+z=47

y+10+y+z=47

2y+z=47-10=37

2(z+8)+z=37

2z+16+z=37

3z=37-16=21

z=21/3=7

y=z+8=7

8=15

x=y+10=5+10=25
