The equation is -2y + 16 = 10
2y+3y-7y+4=16 -2y=12y=-6Check it-12-18+42+4=16-30+46=1616=16
2x + 4y = 16 is the same as 4y = -2x + 16 divide both sides by 4 and you get y = (-x/2) +4 3x - 2y = 6 is the same as -2y = -3x + 6 divide both sides by 2 and you get y = (-3x/2) + 3 therfore they do not have the same solution
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)
Both of them are equations!The solution is (x, y) = (2, 1).
