x = 30
y = 90
Step-by-step explanation:
2x=y-x
y+x+2x=180
Simplify each equation
2x=y-x
Add x to each side
2x+x = y-x+x
3x= y
y+x+2x=180
y+3x= 180
Substitute y = 3x
y + y = 180
2y = 180
Divide by 2
2y/2 =180/2
y = 90
Now solve for x
3x = 90
Divide by 3
3x/3 = 90/3
x = 30
Since we cannot see the angles, we can only solve for x and y
3x = y
