If -2x +14 = 0, -2x = -14, or x = 7.
x = 0 and y = 4
It is a linear equation in x. The equation has the solution x = 0.
2x + y = 25 x + y = 14 Subtract second equation from the first: x = 11 Substitute this value of x in the second equation: 11 + y = 14 ie y = 3
2x - 14 = -2, adding 14 to each side gives 2x = 14 - 2 = 12, dividing each side by 2 gives x = 12/2 Thus x = 6
2x + 5y = 16 -2x - 3y = -14 2y = 2 y = 1 / x = 5.5 (5.5,1) or (5 1/2,1)
If -2x +14 = 0, -2x = -14, or x = 7.
-2x+14=20 x=-3
2x plus 3y
4x + 2 + 2x - 2x = 14 4x = 14 - 2 4x = 12 x = 3
4x + 3 = -3 + 2x + 14 2x + 3 = -3 +14 2x + 3 = 11 2x = 8 x=4
X=14
