Question

5y - 6 = x\
y = -x

Explanation:

Step1: Substitute $y=-x$ into first equation

$5(-x) - 6 = x$

Step2: Simplify left side of equation

$-5x - 6 = x$

Step3: Move $x$ terms to one side

$-5x - x = 6$
$-6x = 6$

Step4: Solve for $x$

$x = \frac{6}{-6} = -1$

Step5: Substitute $x=-1$ into $y=-x$

$y = -(-1) = 1$

Answer:

$x=-1$, $y=1$
