What mistake was made in this equation 3x plus 7 equals -4x plus 28 -x plus 7 equals 28 -x equals 21 x equals -21?
3x + 7 = -4x + 28 implies 7x + 7 = 28
What is the x in the equation -x2 plus 3x plus 2y?
This is only half of an equation. If -x^2 + 3x +2y = 0, then x^2 -3x = 2y and y = (x^2-3x)/2 Solving for x is the inverse, but difficult without a second equation.
What is x if 3x 84?

What is x in this equation 3x plus 4 equals -11?
3x+4=-11 3x=-15 x=-5
What is X squared equals 3X?
It is a quadratic equation in X.
What is the answer to this equation 3x-1 equals 28?
3x - 1 = 28 3x = 29 x = 29/3 x= (approximately) 9.67
Write the quadratic equation in factored formx2 plus 3x-28?
x2 + 3x - 28 = x2 + 7x - 4x - 28 = x(x + 7) - 4(x + 7) = (x + 7)(x - 4)
What is the solution to this equation 3x and ndash 7 plus 4x 28?
If you mean: 3x -7 +4x = 28 then the value of x works out as 5
What mistake was made in this equation 3x plus 7 equals -4x plus 28 -x plus 7 equals 28 -x equals 21 x equals -21?
3x + 7 = -4x + 28 implies 7x + 7 = 28
X² -3x - 28 equals?

What is the equation of the line in point-slope form that passes through the points 9 1 and 4 16?
Points: (9, 1) and (4, 16) Slope: (1-16)/(9-4) = -3 Equation: y-1 = -3(x-9) => y = -3x+28 Equation: y-16 = -3(x-4) => y = -3x+28
