Answer:
(x , y) = (-2 , 1)
Step-by-step explanation:
multiply both sides by -1
sum the equations vertically to eliminate at least one variable
divide both sides by -8
substitute the value of y into the equation
now solve for x using that y=1
Answer:
The common differences is 5
Step-by-step explanation:
The difference is 5. Why? Because 5 is added to each term to arrive at the next term. so ... the difference a2 - a1 = 5.

Answer:
x = -1.5625
Step-by-step explanation:
Solve for x:
-8 x - 12.5 = 0
Add 12.5` to both sides:
(12.5 - 12.5) - 8 x = 12.5
12.5 - 12.5 = 0:
-8 x = 12.5
Divide both sides of -8 x = 12.5 by -8:
(-8 x)/(-8) = 12.5/(-8)
(-8)/(-8) = 1:
x = 12.5/(-8)
12.5/(-8) = -1.5625:
Answer: x = -1.5625
