Answer:
x=1
Step-by-step explanation:
x=-b/(2a)
a=2
b=-4
c=2
-(-4)/(2*2)=4/4 or 1
x=1
Answer:
cannot be simplified anymore
Step-by-step explanation:
b(a+c)
Substituting (x, y) with (a, a), since we have:
3a=2a-4, which means that 3a-2a=-4, that is a=-4.
So, the point is (-4, -4).
Remark: a point which lies in the graph of an equation is a solution of that equation. So x=a, y=a satisfies the equation <span> 3y = 2x -4, which makes our substitution legitimate.
Answer: </span>(-4, -4).
