Question 203725: 2x+y=3,y=4

You can put this solution on YOUR website! 2x+y=3,y=4
Replace the y in the equation with 4 (2x+4=3),then you solve to find out what x is. The next step is to subtract the 4 from both sides (2x = -1) then divide both sides by 2 to solve for x (x = -1/2). To check your equation, put the values for x and y into your equation to see if it equals out:
2x+y=3
2(-1/2)+4=3
(-1)+4=3
3=3
