Question

2x + y = 8

x + y = 4

The lines whose equations are given intersect at

(4, 0)
(0, 4)
all points on the line

Answer 1

\[2x + y = 8\]\[ x + y = 4 \] subtract the second equation from the first in a column
you get \[x=4\]

Answer 2

since \(x=4\) you know \(4+y=4\) and so \(y=0\)
your answer is \((4,0)\)
