Answer:

y = 1

Step-by-step explanation:

So to find the value of y that makes the equation true we have to calculate the value of y.

3y - 5y - (2y - 6) = 8y - 2(9y - 6)

First we have distribute;

3y - 5y - 2y + 6 = 8y - 18y + 12

Collect like terms next;

-4y + 6 = -10y + 12

Add 10y to both sides

6y + 6 = 12

Subtract 6 from both sides

6y = 6

Divide both sides by 6

y = 1

ABCD is a parallelogram. Find the values of x and y. Solve for the value of z, if z=x−y.
slava [35]

Answer:

C

Step-by-step explanation:

Parallel and opposite sides of a parallelogram are equal. Hence, we can say:

x + 30 = 2x - 10

and

2y-10 = y +10

Solving first one, we get:

x + 30 = 2x - 10

30+10 = x

x = 40

Also

2y - 10 = y + 10

y = 10 + 10

y = 20

Now, z = x - y, so

z = 40 - 20 = 20

Answer C is right.
