Answer:
[tex]x=1\\y=1\\\\(1,1)[/tex]
Step-by-step explanation:
Apply the method of substitution:
- Substitute [tex]x=2y-1[/tex] into the first equation:
[tex]2(2y-1)+y=3\\4y-2+y=3\\5y=5\\y=1[/tex]
- Substitute the value of y into the any of the original equations and solve for x, as you can see below:
[tex]1=2y-1\\2=2y\\y=1[/tex]
Then the solution is:
[tex]x=1\\y=1\\\\(1,1)[/tex]
Answer:
The solution is (1,1).
Step-by-step explanation:
We have given a system of equations.
2x+y = 3 eq(1)
x = 2y-1 eq(2)
We have to find the solution of given system.
Putting eq(2) into eq(1), we have
2(2y-1)+y = 3
4y-2+y = 3
4y+y = 3+2
Adding like terms, we have
5y = 5
y = 1
Putting value of y in eq(2) , we have
x = 2(1)-1
x = 2-1
x = 1
Hence , the solution is (1,1).
