Answer:
= 0.125
Explanation:
Combine multiplied terms into a single fraction : −
-0.5z + 1.25= 3.5z +0.75
-z/2 + 1.25 = 3.5z + 0.75
-------------------------------------------------------------------------
Combine multiplied terms into a single fraction
-z/2 + 1.25 =3.5z + 0.75
-z/2 + 1.25=7z/2 + 0.75
---------------------------------------------------------------------------
Subtract 1.25 from both sides of the equation
-z/2 + 1.25 = 7z/2 + 0.75
-z/2 + 1.25 - 1.25 = -z/2+0.75 - 1.25
--------------------------------------------------------------------------
Simplify
Subtract the numbers
-z/2 - 7z/2 - 0.5
------------------------------------------------------------------------------
Multiply all terms by the same value to eliminate fraction denominators
-z/2 - 7z/2 - 0.5
2· -z/2 = 2(7z/2 - 0.5)
----------------------------------------------------------------------------
Simplify
-Cancel multiplied terms that are in the denominator
-Distribute
-Cancel multiplied terms that are in the denominator
-z = 7z- -1
------------------------------------------------------------------------------
Subtract 7z from both sides of the equation
-z = 7z- -1
-z -7z = 7z - -1 -7z
----------------------------------------------------------------------------------
Simplify
-Combine like terms
-Combine like terms
-8z = - -1
----------------------------------------------------------------------------------
Divide both sides of the equation by the same term
-8z = - -1
-8z/-8 = --1/-8
-------------------------------------------------------------------------------------
Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
= 0.125
