Answer

When $x = 1$, $2 \cdot 1 + 3y = 5$; $y = 1$ When $y = 3$, $2x + 3 \cdot 3 = 5$; $x = -2$ When $y = -1$, $2x + 3 \cdot -1 = 5$; $x = 4$ b) Refer to Graph I for the graphing.

Work Step by Step

When $x = 1$, $2 \cdot 1 + 3y = 5$; $y = 1$ When $y = 3$, $2x + 3 \cdot 3 = 5$; $x = -2$ When $y = -1$, $2x + 3 \cdot -1 = 5$; $x = 4$
