So since it’s an equilateral triangle all the angles equal 60 degrees.

7x-3=60
+3 +3
7x=63 /7
X=9

Answer:

no solution (parallel lines)

Step-by-step explanation:

You observe that the coefficient in the second equation are all multiples of 3. Dividing that equation by -3 gives the two equations ...

y = 2x - 11
y = 2x + 5

The slopes are the same (2) and the intercepts are different (-11, 5), so the lines are parallel. There is no solution.
