If 4x = 8, then x = 2
I think this might read "4x+5 = 4x-1". Subtracting 4x from both sides cannot upset the equality, and then you have +5 = -1, which is nonsense. One moral of this is "make sure your equation makes sense, and actually includes an = sign."
It's the equation of a straight line. Every point on the line is a solution to the equation. There are an infinite number of them.
4x - 16 = 64Add 16 to each side of the equation:4x = 80Divide each side by 4:x = 20
Let the unknown number be x: 4x-7 = 13 Moving -7 to the other side of the equation changes it to +7: 4x = 13+7 4x = 20 Divide both sides of the equation by 4 to find the value of x: x = 5

This is a quadratic equation which will have two solutions: X2 = 4x+5 Rearrange the equation: x2-4x-5 = 0 Factor the equation: (x+1)(x-5) = 0 So the solutions are: x = -1 or x = 5

The equation of such a line is [ Y = -4x plus any number].
-4x + 9y = 0 is the equation of a line in the Cartesian plane and the coordinates of any of the infinite number of points on that line will satisfy the equation.
The answer is the number that 'x' must be in order to make the equation true.You said that-4x = 8Now, watch carefully, as I divide each side of the equation by -4 :x = -2
Restate the question: Simplify: (x-3) + 4x(x-3) + 4x = x - 3 + 4x= x + 4x -3= 5x -3=======Answer 1:x - 3 + 4xThat expression is not an equation. It's just a number. The number dependson what the value of 'x' happens to be at the moment, and if 'x' changes, then(x - 3 + 4x) immediately changes. Without an equation, there's no "solution".Your expression would be an equation if there were an 'equals' sign ( = )anywhere in it.
IN equation form, when the number is x: 3x = 6 + 4x 3x - 4x = 6 -x = 6
the equation 6x^2 - 4x + 25 is a quadratic equation due to the 6x^2 term. Whatever number on the x squared term changes it to a quadratic equation if you were to get rid of the 6x^2 then the equation would simply be -4x+25 making it simply a linear equation. when ever you have an x raised to 2 that term is the quadratic term in the equation.
Let the unknown number be x: 4x+12 = 4 4x = 4-12 4x = -8 Divide both sides of the equation by 4 to find the vlue of x: x = -2
Let's represent the unknown number as "x." The quotient of -36 and 9 can be expressed as -36/9. The equation can be written as (-36/9) > 4x + 8. Simplifying, we get -4 > 4x + 8. By further simplifying, we find -12 > 4x, which can be written as x < -3.
