To solve the system of equations, we can use the elimination method.<br /><br />Given:<br />$x + 3y = 1$<br />$-3x - 3y = -15$<br /><br />Step 1: Add the two equations to eliminate $y$.<br />$(x + 3y) + (-3x - 3y) = 1 + (-15)$<br />$-2x = -14$<br />$x = 7$<br /><br />Step 2: Substitute the value of $x$ into the first equation to find $y$.<br />$7 + 3y = 1$<br />$3y = -6$<br />$y = -2$<br /><br />Therefore, the solution to the system of equations is $x = 7$ and $y = -2$.
