x is approximately equal to 0.34 and -4.34

Could you please help me
Dmitrij [34]
∠GBE = y (alternate angles)

∠DBG + ∠GBE = 180 (Adjacent angles on a straight line adds up to 180)
⇒ x + y = 180

∠DBG = ∠ABE (Vertially opposite angles)
⇒ x = 5y - 18

--------------------------------------------------
Solve for x and y :
--------------------------------------------------
x + y = 180 -------- (1)
x = 5y - 18 --------- (2)

Sub (2) into (1) :
5y - 18 + y = 180 
6x = 198
x = 33 --------- Sub into (1)
x + y = 180
33 + y = 180
y = 147

-----------------------------------------------------
Answer: x = 33°, y = 147°
