Step 1: Simplify both sides of the equation.
−4(x+3)=8
(−4)(x)+(−4)(3)=8(Distribute)
−4x+−12=8
−4x−12=8
Step 2: Add 12 to both sides.
−4x−12+12=8+12
−4x=20
Step 3: Divide both sides by -4.
−4x

Answer:
x=−5
A line has no thickness, but it does have direction and infinite length.
A line has length but no width, making it a one-dimensional figure. A line is made up of a collection of points that can be stretched indefinitely in opposing directions.
Given the variety of geometries in modern mathematics, the idea of a line is directly related to how the geometry is described. For instance, a line in the plane is frequently defined in analytic geometry as the collection of points whose coordinates satisfy a given linear equation, but in a more abstract context, such as incidence geometry, a line may be an independent object, distinct from the collection of points that lie on it.
In cartesian plane the general equation of a line is given by :
y=mx+c where the slope is denoted by m and the y-intercept by c.
