Excuse if I have this wrong but I’m going to guess that in every question how the 2 is up the m or the other letters that means you are multiplying that number/ letter by its self one more time so I’m not really sure, I’m sorry.

is (-1/2 x + 6/7) - (7/2 x - 4/7) equivalent to -4 x + 2/7 ? use the properties of operations to justify your answer
LuckyWell [14K]

Answer:

The given equation is NOT justified.

Step-by-step explanation:

Here, the given equation is (\frac{-1}{2}x + \frac{6}{7} )  -  (\frac{7}{2}x - \frac{4}{7} )   = -4x + \frac{2}{7}

Now, here Consider the left hand side and simplifying the left side by operating on the like terms,

⇒(\frac{-1}{2}x + \frac{6}{7} )  -  (\frac{7}{2}x - \frac{4}{7} )   = \frac{-1}{2}x + \frac{6}{7}   -  \frac{7}{2}x + \frac{4}{7}  =  (\frac{-1}{2}x -\frac{7}{2}x) + (\frac{6}{7}   + \frac{4}{7})

=(\frac{-1 - 7}{2}x ) + (\frac{6 + 4}{7} ) = \frac{-8x}{2} + \frac{10}{7}   \neq -4x + \frac{2}{7}

Here, Left side of equation  ≠ Right side of the equation

Hence, (\frac{-1}{2}x + \frac{6}{7} )  -  (\frac{7}{2}x - \frac{4}{7} )   ≠ -4x + \frac{2}{7}
