3 0

Answer:

2(3x+y=4)

1(x+2y=-2)

6x+2y=8

<u>(-) x+2y=-2</u>

<u>5x=10</u>

5

x=2

x+2y=-1

2+2y=-1

<u>-</u><u>2</u><u> -</u><u>2</u>

<u>2y=-</u><u>3</u>

2

y=-3/2

Step-by-step explanation:

  1. multiply the first equation by 2 to make y equal to each other.
  2. subtract to eliminate y
  3. divide by 5 to get x
  4. take one of the equations

Factor completely 3x2 − 11x 8. (x 4)(3x − 2) (x − 2)(3x − 4) (x 1)(3x − 8) (x − 1)(3x − 8).
earnstyle [38]

The factors of the equation 3x^{2} -11x+8 will be (3x-8)(x-1)

<h3>What will be the factors of the given equation?</h3>

When we split the equation into two groups we will get

3x^{2} -3x-8x+8

3x(x-1)-8(x-1)

Now taking (x-1) common

(3x-8)(x-1)

Thus the factors of the equation 3x^{2} -11x+8 will be (3x-8)(x-1)
