The equation is -2y + 16 = 10

y = 5

5x + (3y-x) + (10-2y) = 5x + 3y - x + 10 -2y = 5x - x + 3y - 2y + 10 = 4x + y +10

2y+3y-7y+4=16 -2y=12y=-6Check it-12-18+42+4=16-30+46=1616=16

The solution is:- x = 0 and y = 5

3x + 2y + 5 - 3 = 3x + 2y + 2 No further simplification is possible. This is an expression, not an equation so there cannot be a solution.

y = 0 and x = 8.

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)

It equals a simple linear equation in 'y'. Its solution is 7/3 .

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

Both of them are equations!The solution is (x, y) = (2, 1).

2y+5y=10 7y=10 y=10/7
