Step-by-step explanation:
Answer:
x=4, y=1
Step-by-step explanation:
We can solve this set of equations using elimination.
Multiply the first equation by 3:
![15x-6y=54](https://tex.z-dn.net/?f=15x-6y%3D54)
Multiply the second equation by 5:
![15x+15y=75](https://tex.z-dn.net/?f=15x%2B15y%3D75)
Now we take ![(15x+15y=75)\\ - \\(15x-6y=54)](https://tex.z-dn.net/?f=%2815x%2B15y%3D75%29%5C%5C%20-%20%5C%5C%2815x-6y%3D54%29)
![21y=21](https://tex.z-dn.net/?f=21y%3D21)
Therefore,
.
To solve for x, substitute y=1 into the second equation.
![3x+3y=15](https://tex.z-dn.net/?f=3x%2B3y%3D15)
![3x+3(1)=15](https://tex.z-dn.net/?f=3x%2B3%281%29%3D15)
![3x+3=15](https://tex.z-dn.net/?f=3x%2B3%3D15)
![3x=12](https://tex.z-dn.net/?f=3x%3D12)
Hence,
.

[/tex]
We know that height is 68 inches and weight 141 pounds
We must remember that 1 inches = 2.54 cm and 1 pound 0.453 kg
