Well, honey, if 2y equals -2, then y is simply -1. It's basic algebra, darling, nothing to lose sleep over. So, y equals -1, case closed.
To solve for y in the equation 2y = -2, you need to isolate y by dividing both sides by 2. This gives you y = -2/2, which simplifies to y = -1. Therefore, the value of y in this equation is -1.
x2 - 4y2 = 16∴ (x - 2y)(x + 2y) = 162y - x = 2∴ x = 2y - 2∴ ([2y - 2] - 2y)([2y - 2] + 2y) = 16∴ (y - 1 - y)(y - 1 + y) = 16∴ -1(2y - 1) = 16∴ 1 - 2y = 16∴ -2y = 15∴ y = -7.52y - x = -2∴ -15 - x = -2∴ x = -13So the point of intersection is (-13, -7.5)
(A) 3x + 2y = -2 (B) 6x - y = 6 (A) + 2(B): 3x + 2y + 12x - 2y = -2 + 12 or 15x = 10 or x = 2/3 substitute this value of x in (A) 2 + 2y = -2 2y = -4 and y = -2 Answer: x = 2/3, y = -2

2y+26 = 28 2y = 28-26 2y = 2 y = 1
If you mean: -2y-3-y+2 then it can be simplified to -1-3y
