13 + 7 - (6 + 4) * 2 = 0
3 is the true!
From what i understand the equation is like this; (3 * 2 ) + 6x + 24 = 0 6 + 6x +24 = 0 6x = - 24 - 6 6x = - 30 x = - 5
If you mean: 3x+2y+6 = 0 then it is y = -1.5x-3 as a straight line equation
If you mean 2x -3y = 6 then it is true and so is (3, 0)
6
(9+3) - (2 +4) = 6
Then the straight line equation is: y = -4x+6
It is: 25-4(8*6) = -167
Given, that 4x + 6 = 6x - 12; then, (6x - 12) - (4x + 6) = 0, 2x - 18 = 0, and 2x = 18. Thus, x = 9. Checking, we substitute 9 for x in the equation: 4(9) + 6= 6(9) - 12; whence, 36 + 6 = 54 - 12, and 42 = 42, which is patently true. What this means is that the original equation is true exactly when x = 9; otherwise, it is false. We call 'x = 9' the solution to the given equation.
x2- 7x + 6 = 0 factor, (x-6)(x-1) = 0 x = 6 x = 1
Equation: 6x^2 +2x +k = 0 Using the discriminant formula: k = 1/6 Using the quadratic equation formula: x = -1/6 Check: 6(-1/6)^2 +2(-1/6) +1/6 = 0
