A system of equations is graphed on the coordinate plane. y=−6x−3y=−x+2 What is the solution to the system of equations? Enter t
Mamont248 [21]
If you equate both, the y is eliminated:

-6x-3 = -x+2

Simplify this to find x:

-5x = 5
x = -1

Fill in x=-1 in either equation:

y = --1 + 2 = 3

So (-1,3) is the solution, it is where the lines intercept.

Y=3xy-1, Solve for y
Ket [755]

Answer:

y = \frac{1}{3x-1}

Step-by-step explanation:

Given

y = 3xy - 1

Collect terms in y on the left side by subtracting 3xy from both sides

y - 3xy = - 1 ← factor out y on the left side

y(1 - 3x) = - 1 ( divide both sides by 1 - 3x

y = \frac{-1}{1-3x} ← multiply numerator/denominator by - 1

y = \frac{1}{3x-1}

The numbers that satisfy the equation a =5.
madam [21]
<h2>Explanation:</h2>

We use an equation to say that two things are equal. An equation always has an equal sign "=". So an equation tells us that the left side is equal to the right side. In this case, we have the following equation:

a =5

So the only value that makes this equation to be true is 5, because:

5=5

For instance, let's choose another value, say, 8. So substituting:

6 =5 \ \text{So this statement is false because} \ 6\neq 5

Explain how you can use absolute value to tell wether the sum of two integers is positive or negative
Rudiy27

Step-by-step explanation:

Using absolute value to tell wether the sum of two integers is positive or negative.

Suppose we have a positive integer,

x and a negative interger, -x and we want to find their sum, we take the absolute values of each of the integers, that is |x| and |-x|. Then we subtract these values: |x| - |-x|. If the larger integer is positive, the result of the difference is positive, but if the larger number is negative, the result of the difference is negative.

For any integer x, x + (-x) = 0
