Answer:
The Answer is: y = -2x + 7
Step-by-step explanation:
2x + y = 7
Subtract 2x from both sides:
y = -2x + 7
Looking at <span>4x3 + x2 – 8x – 2, I see immediately that x^2 can be factored out of the first 2 terms => 4x^2(x+1)
and -2 out of the last 2 terms => -2(4x+1).
Notice how the factor (4x+1) shows up twice.
We can factor this (4x+1) out, obtaining (x^2 - 2) (4x+1). These are the desired factors, found "by grouping."

Putting this into an equation, it would be (12 ÷ -3) + - (14 x 4)
-4 + -56 = -60
5x - 3x + 4 = -4 +20
2x + 4 + 16
subtract 4 from each side
2x=12
divide each side by 2
x=6
