-3(-4x + 2y = 12) 2(-13x + 3y = 46) 12x -6y = -36 -26x + 6y = 92 12x - 6y = -36 -26x + 6y = 92 -14x 0 = 56 -14x/-14 = 56/-14. X = -4. -4x + 2y = 12 -4(-4) + 2y = 12 16 + 2y = 12 -16. -16 2y/ 2 = -4/2 Y = -2 -4x + 2y = 12 -4(-4) + 2(-2) = 12 16 -4 = 12 12 =12 (-4,-2)

because it is arithmetic not geometric
14,x,56
An = An-1 + d
x = 14 +d --> d = x-14
56 = x +d --> d = 56-x
By substitution
x-14 = 56-x
2x = 70
x = 35
the sequence is 14,35,56
