∠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°

Answer:
Y=1, X= -(4/3)
Step-by-step explanation:
Y=6X+7
3X-8Y=4
Substitute Y=6X+7
3X-8Y=4
3X-8(6X+7)=4
3X-48X-56=4
-45X-60=0, therefore 45X=-60=X=-4/3
Sub. X values in Equation
Y=6X+7
=6(-4/3)+7, therefore Y=-1
