Answer:
A) 6
Step-by-step explanation:
-110= -2(8x+7)
Divide both sides by -2
55 = 8x+7
Subtract both sides by 7
48 = 8x
Divide both sides by 8
6 = x
The system of equations is
x - 2y = 2 (1)
3x + y = 6 (2)
From (1), obtain
x = 2y + 2 (3)
Substitute (3) into (2).
3(2y + 2) + y = 6
6y + 6 + y = 6
7y = 0
y = 0
From (3), obtain
x = 2*0 + 2 = 2
Answer: (2, 0) or x=2, y=0
