Just find the GCF of the numerator and the denominator after multiplying across.
Im pretty sure it’s angle EFD
The terminating is number is b
your answer would be 2x - y + 3 = 0
1) I )-3X-4Y = -2
Y = 2X-5, substitute it in I
-3X-4(2X-5) = -2 ⇒-3X-8X+20 = -2⇒-11X = -2-20 ⇒(-1) -11X = -22 ⇒11X= 22⇒X= 22/11 ⇒X= 2
