Ineed ! graph the following system of equations. what is the solution set? 2x + y = 3 x = 2y - 1

It looks like I could substitute the x=2y-1. Into 2x+y=3
2(2y-1)+y=3
4y-2+y=3
5y=5
y=1
x=2(1)-1
x=1
  (1,1)
CHECK
2x+y=3
2(1)+(1)=3
2+1=3
3=3
Left hand side=Right hand side 
Check other equation 
x=2y-1
1=2(1)-1
1=1
Therefore the solution is (1,1). Since the left hand side= right hand side in each equation

Alr cool i like typing things ; ; ! & : 9: & : & : & & 392: ; ! ,@: 929: & : 83$:
