Mathematics

X+2y=8
2y=8-x |:2
y=-\frac{1}{2}x+4
y=ax+b ==> y=-\frac{1}{2}x+4
We calculate the zeros of functions (0,b)
(0,b) = (0,4)
We have solution:
x=0, y=4

<em>If we put x = 0, we get</em>
<em>0 + 2y = 8</em>
<em>=> y = 8 / 2 = 4</em>

<em>if we put y = 0</em>
<em>x + 2 ( 0 ) = 8</em>
<em>=> x = 8</em>

<em>It means that solution set is { (0,4) , ( 8,0 ) }</em>
