Answer:
X = -2
y = 2
Step-by-step explanation:
Substitute y=x + 4 in the second equation to find x
x+4 = 2x + 6
subtract x from both sides
4 = x + 6
subtract 6 from both sides
-2 = x
put -2 in for x in the first equation
y= 2
Answer:
D
Step-by-step explanation:
Since GH and JK are congruent then the central angles are congruent, that is
∠KOJ = ∠HOG = 68° → D
Subtract the two equations: 8y=0
y=0
x=-8
