Your first goal is to get all the X’s to one side of the equation.

So:

3x - 5 = 9x + 8 - 5x

+5x +5x

8x - 5 = 9x + 8

-9x -9x

-1x - 5 = 8

Now that you have all the X variables simplified and on one side, you make sure all of you constant terms are on the other side.

-1x - 5 = 8

+5 +5

-1x = 13

Because you can’t have a negative X, you divide the entire equation by -1.

<u>-1x = 13</u>

-1

x = -13

Dividing by -1 will give you the inverse of the equation which is <u>positive</u> one x equals <u>negative</u> thirteen.

Andre45 [30]

Answer:

Step-by-step explanation:

Given

there are six integers to win a lottery

case-1 Integer not exceeding 40

no of ways to choose 6 incorrect numbers

=\dfrac{^{34}C_{6}}{^{40}C_{6}}

=0.35

Case-2 no of ways to choose 6 incorrect numbers out of 48 integers

=\dfrac{^{42}C_{6}}{^{48}C_{6}}

=0.427

Case-3 no of ways to choose 6 incorrect numbers out of 56 integers

\dfrac{^{50}C_{6}}{^{56}C_{6}}

=0.489

Cae-4 no of ways to choose 6 incorrect numbers out of 64 integers

\dfrac{^{58}C_{6}}{^{64}C_{6}}

What is the equation if x=1 and y=16/3
GaryK [48]
There may be more than one way in which to answer this question.  I will assume that the "equation" is a linear one:  f(x) = mx + b.

Then (16/3) = m(1) + b
This is one equation in two unknowns, so it does not have a unique solution.  Was there more to this problem than you have shared?


If we assume that the y-intercept (b) is zero, then y = mx, and 

16/3 = 1m, so that m = 16/3, and so   y = (16/3)x.
