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

Solve for d.<br> 85 = 5(d − 68)
Talja [164]

Answer:

Step-by-step explanation:

5(d - 68) = 85

Use distributive property

5*d - 68*5 = 85

5d - 340 = 85

Add 340to both sides

5d = 85 + 340

5d = 425

Divide both side by 5

d = 425/5

d = 85
