-\frac{5}{3}-\frac{1}{3}x=1-x
Substitute -\frac{5}{3}-\frac{1}{3}x for y in the equation y=1-x.
x=4 a=-x
Solve the second equation for x and the third equation for a.
a=-4
Substitute 4 for x in the equation a=-x.
y=-\frac{1}{3}\times 4-\frac{5}{3}
Substitute 4 for x in the equation y=-\frac{1}{3}x-\frac{5}{3}.
y=-3
Calculate y from y=-\frac{1}{3}\times 4-\frac{5}{3}.
y=-3 x=4 a=-4
The system is now solved.
