Answer:
<em>x = 1</em>
<em>y = 1</em>
Step-by-step explanation:
<u>System of Equations</u>
We are given the system of equations:
2x + y = 3
x = 2y - 1
Substituting x in the first equation:
2(2y - 1) + y = 3
Operating:
4y - 2 + y = 3
5y = 3 + 2
y = 5/5 = 1
y = 1
Since:
x = 2y - 1
Then:
x = 2(1) - 1
x = 1
Solution:
x = 1
y = 1
1 and a half tons of gravel is 3000 pounds, so do 3000-1750 and get 1250 pounds of gravel.
Answer:
Y: 2
E: 9
A: 1
R: 0
Step-by-step explanation:
If we used the value Y = 2,
E = 9 ,
A = 1 and R = 0
in the given equation i.e
.
From LHS,
Putting the value of Y,E, A and R in the given question we get
![2222-999+11-0\\=\ 1223\ + 11\\=\ 1234](https://tex.z-dn.net/?f=2222-999%2B11-0%5C%5C%3D%5C%201223%5C%20%2B%2011%5C%5C%3D%5C%201234)
=RHS
![Therefore\ the\ value\ of \ Y, E, A, R\ is\ 2\ , \ 9 , \ 1\ and\ 0](https://tex.z-dn.net/?f=Therefore%5C%20%20the%5C%20%20value%5C%20%20of%20%5C%20%20%20Y%2C%20E%2C%20A%2C%20R%5C%20%20is%5C%20%202%5C%20%2C%20%5C%20%209%20%2C%20%5C%201%5C%20%20%20and%5C%20%200)
