To explain about an equation having absolute value.
following steps for Solving equation involving absolute value
(a) Isolate the absolute value expression
(b)set the quantity inside the absolute value notation equal to + and - the quantity on the other side of the equation
(c) solve for the unknowns in both the equations
(d) now check the answer graphically and analytically
The absolute value is already isolated either 2x+1=5 or 2x-1=-5
now solve the equation
check the solutions by substituting in the equation
therefore x = -2,3 are two solutions.
