Answer:
x=7
y=2
Step-by-step explanation:
x-3y=1 ...(1)
3x-5y=11 ...(2)
subtract first from second eq.
3x-5y-(x-3y)=11-1
3x-5y-x+3y=10
2x-2y=10
x-y=5 ...(3)
(3)-(1) gives
2y=4
y=4/2=2
from (3)
x-2=5
x=5+2=7
Do you mind typing the equation it looks incomplete.
∠1 = 144°
∠2 = 144°
∠3 = 36°
∠4 = 90°
∠5 = 144°
∠6 = 36°
∠7 = 144°
∠8 = 90°
x=-2;y=-7
y=5x+3
y=3x-1
3x-1=5x+3
-2x=4
x=-2 y=5x+3 y=5×(-2)+3 y=-7
y=-9x+35
