Answer:
<h2>x=2 y=6</h2>
Step-by-step explanation:
x+y= 8
there are lots of pairs
y= 2x+2
there are lots of possibilities
but if
x+y=8 when y= 2x+2
then you plot both of these lines on a graph
you can do this by replacing
x by other numbers in both of the equations
i have done this and i found out x=2 and y=6
Answer:
x=2, y=6
Step-by-step explanation:
If you would like you do not have to do it by graphing.
Since y = 2x+2 you can plug in 2x+2 for y in the first equation:
x+2x+2=8
3x+2=8
3x=6
x=2
Now plug 2 into either equation.
y=2x2+2
y=4+2
y=6
