Step-by-step explanation:
3x²-3x+x-1=0
3x(x - 1) + 1(x - 1) = 0
(x - 1)(3x + 1) = 0
Either x - 1- = 0, then x = 1
or 3x + 1 = 0, then x = -1 3
x = 1 or -1 3

Step-by-step explanation:
3y + 4 = 11y
(take away 3y from both sides)
4 = 8y
(divide by 8 on both sides)
0.5 = y
y = 0.5

Answer:
y-6 = -2(x+1)
Step-by-step explanation:
First we need to find the slope
m = (y2-y1)/(x2-x1)
= (-2-6)/(3--1)
= (-2-6)/(3+1)
= -8/4
= -2
Then we can point slope form where
y -y1 = m(x-x1)
where m is the slope and x1,y1 is a point
y-6 = -2(x--1)
y-6 = -2(x+1)
