Answer:
[tex] - 2x + 4x = 2 \\ 2x = 2 \\ x = 1 \\ \\ 1 + y = 2 \\ y = 1[/tex]
Answer:
[tex]x=1\\y=1[/tex]
Step-by-step explanation:
Solve by substitution:
[tex]x+y=2\\-2x+4x=2[/tex]
[tex]2x=2;x+y=2[/tex]
Solve [tex]2x+2[/tex] for x:
[tex]2x=2[/tex]
[tex]x=2/2[/tex]
[tex]x=1[/tex]
Substitute 1 for x in [tex]x+y=2[/tex]
[tex]x+y=2[/tex]
[tex]1+y=2[/tex]
[tex]y=2-1[/tex]
[tex]y=1[/tex]
[tex]x=1[/tex] & [tex]y=1[/tex]
hope this helps...
