Answer:

$u=-\frac{6}{7} w$

Step-by-step explanation:

$4u+8w=-3u+2w$

Add $3u$ and $-8w$ on both sides.

$4u+3u=2w-8w$

Add or subtract like terms.

$7u=-6w$

Divide $7$ on both sides.

$7u/7=-6w/7$

$u=-\frac{6}{7} w$

$u$ is the independent variable now.

Solve by combining equations <br> PLS HELP!<br> 3x - 2y = 12<br> -3x+8y= -6

3x−2y=12;−3x+8y=−6

Step: Solve3x−2y=12for x:

3x−2y=12

3x−2y+2y=12+2y(Add 2y to both sides)

3x=2y+12

2y+12

(Divide both sides by 3)

y+4

Step: Substitute

y+4forxin−3x+8y=−6:

−3x+8y=−6

−3(

y+4)+8y=−6

6y−12=−6(Simplify both sides of the equation)

6y−12+12=−6+12(Add 12 to both sides)

6y=6

(Divide both sides by 6)

y=1

Step: Substitute1foryinx=

y+4:

y+4

(1)+4

(Simplify both sides of the equation)

and y=1

Answer:

1. Car Mart sell 11 cars per day.

You can use the table by looking at day 2 and day 3. You can see underneath it, it shows how many cars is left after that particular day. So from day 2, you have 43 cars left and day 3, you got 32 cars left. From 43 car to 32 car is losing 11 car. So each day the Car Mart sell 11 car.

2. First we know that after 3 days, Winston have 32 cars left and after 5 day, it has 12 cars left.

Write an augmented matrix for the following system of equations

chubhunter [2.5K]

Just use the coefficients for each variable and put it in a matrix. Is the second question set equal to something? Because then you would put it in place as the question mark. (Did the pic come through?)
So the 3x3 matrix is made up of the coefficients and then to augment the matrix, you add another column at the end with the solutions. Good luck!
