3x+3=3y ⇒ 3y-3x=3 ⇒3(y-x)=3 ⇒ y-x=1
2x-6y=2 ⇒ 2(x-3y)=2 ⇒ x-3y=1
We must to collect two equations.
x's is lost;
y-3y=2
-2y=2
y=-1 ; x-3.(-1)=1 ⇒ x=-2
Answer is (-2,-1)

Answer:
x=4units
Step-by-step explanation:
area of triangle=1/2×base×height
12=1/2×6×x
x=12/3=4
Answer:
y=mx+b, y=-3x+4
Step-by-step explanation:
so we already know the m or the slope and now we only need to find the b or the y intercept
let’s take -3 and plug it into the equation y=mx+b
y=-3(x)+b
Now let’s take (0,4) and plug that into y=-3(x)+b
4=-3(0)+b
4=b
Now let’s put it all together so
y=-3x+4
