6x − 3y = 42 6x + 8y = 20

Mathematics
1 answer:

Answer:

X= 6, y= -2

Step-by-step explanation:

Let 6x-3y=42------------(1)

6x + 8y =20---------(2)

Subtract (1) from (2) we have

(2) - (1)

6x-6x + 8y - (-3y) = 20 -42

11y = -22

y = -22/ 11 = -2

From (1)

6x - 3y =42

6x - 3(-2) = 42

6x + 6 = 42

6x = 42- 6

6x = 36

x= 36/6 = 6

Answer:

Step 1: Distribute -2 to 5x and 8

Step 2: Subtract from both sides of the equation 6x

Step 3: Add to both sides of the equation  16

Step 4: Divide both sides of the equation by -16

Step-by-step explanation:

Step 1: Apply the Distributive Property. Then you must  distribute -2 to 5x and 8

Then:

-2(5x+8)=14+6x\\\\-10x-16=14+6x

Step 2: You must apply the Subtraction property of Equality and subtract 6x from both sides of the equation. Then:

-10x-16-6x=14+6x-6x\\\\-16x-16=14

 Step 3: You must apply the Addition property of Equality and add 16 to both sides of the equation. Then:

-16x-16+16=14+16\\\\-16x=30

Step 4: You must apply the Division property of Equality and divide both sides by -16. Then:

\frac{-16x}{-16}=\frac{30}{-16}\\\\x=\frac{30}{-16}\\\\x=-\frac{15}{8}

Answer:

Step-by-step explanation:

slopes and equations:

find the  equation thur ( 6,1 )  and (-2,-3)

find the slope m

m = (y2-y1) / (x2-x1 )

m = (-3 - 1) / (-2 -6)

m = -4 / -8

m = 1/2

now use the point-slope formula with our known slope

y-y1 = m(x-x1)

y-1 = 1/2(x-6)

y - 1 = 1/2x -3

y = 1/2x -3 +1

y = \frac{1}{2}x -2

Find the equation parallel to y = 3x + 6 and thur (0,1)

Parallel means the same slope, the slope is 3 for the equation above.

use the slope-intercept formula again with the point given and the slope 3

y-1 = 3(x -0)

y - 1 = 3x

y = 3x +1

Find the equations perpendicular to 2x + y = 8 and the same y intercept as  4y = x + 3.

put both equations into proper form

y = -2x +6

y = \frac{1}{4}x + \frac{3}{4}

perpendicular means  reciprocal slope and change the sign, the 2nd equation has an intercept of  \frac{3}{4} , so

y = 1/2x + \frac{3}{4}

there you go Amanda  :)
