Answer:

x = 65

y = 32

Explanation:

2x + (x - 15) = 180

2x + x - 15

3x - 15 = 180

+15 +15

-------------------

3x = 195

÷3 ÷3

----------------

x = 65

4y + (y + 20) = 180

4y + y + 20 =180

5y + 20 = 180

-20 -20

---------------------

5y = 160

÷5 ÷5

---------------

y = 32

2x + (x - 15) + 4y + (y + 20) = 360

2(65) + (65 - 15) + 4(32) + (32 + 20) = 360

130 + 50 + 128 + 52 = 360

180 + 180 = 360

360 = 360

I hope this helps!

Answer:

x=65

y=32

Explanation:

2x+x-15=180

combine like terms

3x-15=180

add 15 to both sides

3x=195

divide both sides by 3

x=65

now y's

4y+y+20=180

combine like terms

5y+20=180

subtract 20 from both sides

5y=160

divide both sides by 5

y=32
