A number is multiplied by -3 and then this product is decreased by 7. The result is 4 less than twice the opposite of the number. what is the number?

The answer to this question is -3. The equations work out to be -3n-7=-2n-4, and then you can just work it out for yourself.

what is the form y=mx +b for C = {(x, y): (6, 15), (8, 21), (10, 27)

But now, both sides of the equation are different number set equal to each other if you plug -3/5 in for x. That just don’t work.

To solve this problem, let's break it down step by step:

1. Let's assume the number we're looking for is represented by "x".

2. The first step is to multiply the number by -3. This can be expressed as -3 * x, which is -3x.

3. Then, we need to decrease this product by 7, which gives us -3x - 7.

4. The result is said to be 4 less than twice the opposite of the number. The opposite of "x" is "-x", and twice the opposite is 2 * (-x), which is -2x.

5. From the statement, we know that -3x - 7 is 4 less than -2x. We can express this as -2x - 4 = -3x - 7.

Now, let's solve for "x":

-2x - 4 = -3x - 7

To eliminate the x-term on the right side, we can add 3x to both sides:

-2x + 3x - 4 = -3x + 3x - 7

This simplifies to:

x - 4 = -7

Next, to isolate the "x" term, we can add 4 to both sides:

x - 4 + 4 = -7 + 4

Simplifying further, we have:

x = -3

Thus, the number we're looking for is -3.

-3/5 because -3x - 4= 2x-4
