It would first be 0.7 and then 1.1
8x + 7y = 39
4x - 14y = -68
(multiply each term in second equation by -2)
8x + 7y = 39
-8x + 28y = 136
(add both equations)
35y = 175
(divide both sides by 35)
y = 5
(substitute value of y in one of the equations)
8x + 7(5) = 39
8x + 35 = 39
8x = 4
x = 1/2
(x, y) = (1/2, 5)
Answer:
either (-1,-1) or (-4,-4)
Step-by-step explanation:
Answer:
let common difference be d.
a 18=a+17 d
a 14=a+13 d
a+17d - (a+13d) =32
a+17d - a - 13d =32
17d - 13d = 32
4d = 32
d=32/4
d=8
common difference=8
