Solve the system.
$$\begin{aligned}
- 3 x + 15 y & = 3 \
x & = 5 y - 1
\end{aligned}$$
A) $( 9,2 )$
B) $\left( 0 , \frac { 1 } { 5 } \right)$
C) Infinitely many solutions; $\left\{ ( x , y ) \mid y = \frac { 1 } { 5 } x + \frac { 1 } { 5 } \right\}$; dependent system
D) No solution; { } ; inconsistent system

The system is dependent, so it has infinitely many solutions. The solution set is $\left\{ ( x , y ) \mid y = \frac { 1 } { 5 } x + \frac { 1 } { 5 } \right\}$.

Solve the System −3x+15y=3x=5y−1\begin{aligned}- 3 x + 15 y & = 3 \\x & = 5 y - 1\end{aligned}−3x+15yx​=3=5y−1​
