<span>(6x4y3) = 6(-1) *4(3)*3 = -6 * 12 * 3 = -216

if y3 = y^3 then

</span>(6x4y^3) = 6(-1) *4(3)^3 = -6 * 4 * 27= -648

Which statements are true about the ordered pair (5, −6) and the system of equations? {x+y=−1 3x−y=21 Select each correct answer
Likurg_2 [28]

The correct options are:

The ordered pair (5, −6) is a solution to the first equation because it makes the first equation true.

The ordered pair (5, −6) is not a solution to the system because it makes at least one of the equations false.

Step-by-step explanation:

Given equations are:

x+y=-1\\3x-y=21

first of all we have to put the point in both equations to check if the point holds true on both equations

So,

Putting the point in the first equation

x+y=-1\\5-6=-1\\-1=-1

Putting the point in second equation

3x-y=21\\3(5)-6=21\\15-6=21\\9\neq 21

So,

The correct options are:

The ordered pair (5, −6) is a solution to the first equation because it makes the first equation true.

The ordered pair (5, −6) is not a solution to the system because it makes at least one of the equations false.

6-8x=7x-10x-24 solve for x
lana66690 [7]

Answer:

x = 6

Step-by-step explanation:

Let's solve your equation step-by-step.

6−8x=7x−10x−24

Step 1: Simplify both sides of the equation.

6−8x=7x−10x−24

6+−8x=7x+−10x+−24

−8x+6=(7x+−10x)+(−24)(Combine Like Terms)

−8x+6=−3x+−24

−8x+6=−3x−24

Step 2: Add 3x to both sides.

−8x+6+3x=−3x−24+3x

−5x+6=−24

Step 3: Subtract 6 from both sides.

−5x+6−6=−24−6

−5x=−30

Step 4: Divide both sides by -5.

−5x/-5 = -30 /-5

x=6
