Asap pls help i stink at math :(

D. x= 28, 2=23; Use corresponding and supplementary angles.

Step-by-step explanation:

The degrees of (5y-4)° and 3y° both (added together) sum up to 180 degrees.

So the equation would be: (5y-4)+3y= 180.

Step 1- Add common variables.

(5y+3y)-4= 180

8y-4= 180

Step 2- Add 4 to both sides.

8y-4= 180

   +4    +4

8y= 184

Step 3- Divide both sides by 8.

8y= 184

8     8

y= 23

Now that we know what the variable y equals to, we can now solve for x. The equation would be: 3y=(2x+13).

Step 1- Substitute the known variable.

3(23)=2x+13

69= 2x+13

Step 2- Subtract 13 to both sides.

69= 2x+13

-13         -13

56= 2x

Step 3- Divide both sides by 2.

56= 2x

2     2

x= 28

Hope this helps! :)
