<span>x + 3y= -11 (1)
</span><span>-9y = 33 + 3x ---->3x + 9y = -33 (2)
divide (2) equation by 2
</span>3x + 9y = -33
x + 3y = -11 (2')
and equation (1) is also x + 3y= -11 (1)
so
x + 3y= -11 (1)
x + 3y= -11 (2')

Answer:
a) (-2,-1) b) (-3,0) & (-1,0)
Step-by-step explanation:

For the second part, the roots of the equation are simply when the graph crosses the x-axis. This happens twice, at (-3,0) and (-1,0)
