Equivalent form of the first equation that eliminates x when added to the second
To do this, we simply make the coefficients of x to be opposite in both equations.
In the second equation, the coefficient of x is 8.
So, we need to make the coefficient of x -8, in the first equation.

Multiply by -10
![-10 * [\frac{4}{5} x-\frac{3}{5}y=18]](https://tex.z-dn.net/?f=-10%20%2A%20%5B%5Cfrac%7B4%7D%7B5%7D%20x-%5Cfrac%7B3%7D%7B5%7Dy%3D18%5D)

<em>When this is added to the first equation, the x terms becomes eliminated</em>

Step-by-step explanation:
Answer:
3x - y = -1
Step-by-step explanation:
Standard form of equation is Ax + By = C
y - y1 = m (x -x1)
y - 7 = 3 (x - 2)
y - 7 = 3x - 6
3x - y = -7 +6
3x - y = -1
2x^3 - 2x - 4
3x + 1 6x^4 + 2x^3 - 6x^2 - 14x - 1
6x^4 + 2x^3
-6x^2 - 14x - 1
-6x^2 - 2x
-12x - 1
-12x - 4

3x + 1 is not a factor of the dividend because, dividing the dividend with 3x + 1 gives a remainder.
