Answer:

LEFT

k + 3 = 20,

k = 17

RIGHT

3x + 5 = 32,

k = 9

Step-by-step explanation:

For the left side, you have k + 3 on one side equaling 20, so the equation is

k + 3 = 20

To solve is as follows

k + 3 = 20

  - 3    - 3

     k = 17

For the right side,

You have 3 x's and 5 1's right? Adding them together will equal 32 (Other side

So your equation is 3x + 5 = 32

To solve is as follows

3x + 5 = 32

    - 5     -5

      3x = 27

Dividing both sides by 9 we get x = 9

Reasoning; you want to cancel out everything with x so that you got x alone on one side.

Hope this helps, if not comment on this telling me which step I did that you dont understand and I'll explain it.

Hey!

Hope this helps...

~~~~~~~~~~~~~~~~~~~~~~~~~~

So we know that all the denominators are multiples of 3, and the numerators are multiples of 2...

we also know that the fraction 5/6 is a dummy fraction (which means, it will not help us at all)

We know that the numerators (from 5/9 and on), are constantly multiplied by 2, and the denominators (from 5/9 and on) are constantly multiplied by 3...

So by this information, we know that the answer must be 40/243

This is because 20 * 2 = 40

And 81 * 3 = 243

So... put them together, and you get 40/243

The answer is no solution.

Explanation:
Because of pemdas, first, solve the parentheses. It becomes 4.2x + 3, as multiplying by 0.5 caused the same effect as if you were to divide by 2. Now if you look at the problem, it is just 4.2x - 3 = 4.2x + 3. Even though the symbols are different, they are still equal to eachother.

Isolate for x, y = mx + b
zavuch27 [327]

Answer:

x = (y - b)/m

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First subtract b from both sides:

y = mx + b

y (-b) = mx + b (-b)

y - b = mx

Next, divide m from both sides:

(y - b)/m = (mx)/m

x = (y - b)/m

x = (y - b)/m is your answer.
