To find the x-intercepts algebraically, we let y = 0 y=0 y=0 in the equation and then solve for values of x. In the same manner, to find for y-intercepts algebraically, we let x = 0 x=0 x=0 in the equation and then solve for y.

Solve for x.<br><br> 6x - 3 = 21 - 2x<br><br> (SHOW YOUR WORK)
patriot [66]

Answer:

Simplifying

6x + -3 = 21 + -2x

Reorder the terms:

-3 + 6x = 21 + -2x

Solving

-3 + 6x = 21 + -2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2x' to each side of the equation.

-3 + 6x + 2x = 21 + -2x + 2x

Combine like terms: 6x + 2x = 8x

-3 + 8x = 21 + -2x + 2x

Combine like terms: -2x + 2x = 0

-3 + 8x = 21 + 0

-3 + 8x = 21

Add '3' to each side of the equation.

-3 + 3 + 8x = 21 + 3

Combine like terms: -3 + 3 = 0

0 + 8x = 21 + 3

8x = 21 + 3

Combine like terms: 21 + 3 = 24

8x = 24

Divide each side by '8'.

x = 3

Simplifying

x = 3

Helga [31]

Answer:

P (black marble) =3/11

Step-by-step explanation:

We need to find the total number of marbles

4 black marbles+ 2 red marbles+ 6 white marbles= 12 marbles

We take away a black marble and throw it away

3 black marbles+ 2 red marbles+ 6 white marbles= 11 marbles

The probability of drawing a black marble is

P (black marble) = black/total

                           =3/11
