Answer:
there are no solutions
Step-by-step explanation:
x-3y=-3
-2x+6y=12
multiply the first equation by 2
2( x-3y)=-3*2
2x-6y = -6
add the 2 equations together
2x-6y = -6
-2x+6y=12
-------------------
0 = -6
this is not true
so there are no solutions

Answer:
x = 8
y = 6
Step-by-step explanation:
First and foremost, it's an equilateral triangle, therefore all sides and angles are equal.
Knowing that the sum of angle in a triangle is 180°, therefore each angle is 60°.
Then equating (7x+4)° to 60, we have that,
7x+4=60
7x=60-4
7x=56
x=56÷7
x=8.
