Knowing 6x-y above 4y=2,calculate x and y.
bagirrra123 [75]

Answer:

x= 0.083   y = 0.5

Step-by-step explanation:

step 1:

equation 1: 6x -y

equation 2 : 4y = 2

from equation (2)  4y = 2, we calculate value of y to get x

4y = 2 ... divide both sides by 4

<u>4y </u>= <u>2</u>

4      4       y =  1 /2.   y = 0.5

Step 2:

input the value of  y into the equation 1 to get x.

6x - y = 0

6x - 0.5 = 0

6x- 0.5 + 0.5  = 0 + 0.5   ( Add both sides of the equation by 0.5)

6x = 0.5.... divide both sides of the term by 6

<u>6x   </u>=  0.5

6           6

x =  0.083

therefore, y = 0.5 and x = 0.0833

Given m||n, find the value of x. (4x-7) degrees (3x+9) degrees It's transversal problems with equations Can anyone help please
Ratling [72]

Answer:

See explanation

Step-by-step explanation:

Given

\angle 1 = 4x - 7

\angle 2 = 3x + 9

Required

Find x

The question is incomplete, as the relationship between both angles is not given

(1) If they are supplementary, then

\angle 1 + \angle 2 = 180

3x + 9 + 4x - 7 = 180

Collect like terms

3x + 4x = 180+7-9

7x = 178

Divide both sides by 7

x = 25.43

(2) If they are complementary, then

\angle 1 + \angle 2 = 90

3x + 9 + 4x - 7 = 90

Collect like terms

3x + 4x = 90+7-9

7x =88

Divide both sides by 7

x = 12.57

(3) If they are vertically opposite angles, then

\angle 1 = \angle 2

So, we have:

4x - 7 = 3x + 9

Collect like terms

4x - 3x = 9 +7

x = 16
